Silicon 2,8,4 d. Boron 2,3 e. Carbon 2,4. Question 17 What property do all elements in the same column of the periodic table as fluorine have in common? Solution: These elements all have 7 electrons in their outermost shells and these often exist as salts, combined with elements from the Alkali metal group.

Question 18 An atom has electronic configuration 2,8,7. What is the atomic number of this element? Question 19 Which type of ion, cation or anion, will be formed by element A?

Anion will be formed by element A. Question 20 Nitrogen atomic number 7 and phosphorus atomic number 15 belong to group 15 of the periodic Table. Solution: Electronic configuration � Nitrogen � 2s 2 2p 3 and Phosphorus � 1s 2 2s 2 2p 6 3s 2 3p 3. Nitrogen will be more electronegative; this is because its atom has small size due to which the attraction of its nucleus for the incoming electron is more.

Question 21 How does the electronic configuration of an atom relate to its position in the Modern periodic table? Solution: The electronic configuration of an atom increases in the outermost valence shell which relates to its position in the Modern periodic table. Question 22 In the Modern periodic table, calcium atomic number 20 is surrounded by elements with atomic numbers 12, 19, 21 and Solution: The atomic number of calcium is 20, so its electronic configuration is 2, 8, 8, 2.

Which of the given elements A, B, C, D and E with atomic number 2, 3, 7, 10 and 30 respectively belong to the same period? Since, 2nd period has elements having atomic number 3 to Question 5.

Which pair of elements belong to the same group? Elements which differ in atomic number by 8, i. Question 6.

Which one of the following elements found a place in the periodic table later? Question 7. Which of the following are the characteristics of isotopes of an element? Question 8. Which of the following elements would lose an electron easily?

But out of K and Na, K will lose electron more easily because the force of, attraction on valence electron of K is least among the given elements. Question 9. Which among the following elements has the largest atomic radii? Na and K are in the same group and K is below Na, so K will have higher atomic radius, i. In a period on moving left to right, atomic radius decreases. Since, K and Ca are in the same period and K is in 1st group and Ca is in 2nd group, so atomic radius of K will be more than Ca, i.

Also Na and Mg are in the same period, but Na belongs to 1st group and Mg belongs to 2nd group, so atomic radius of Na is more than Mg, i. Hence, we can say that the atomic radius of K is largest. Question Which of the following statements is not a correct statement about the trends when going from left to right across the periods of periodic table? With the increase of nudear charge, the force binding the electron increases so the atom lose the electrons with more difficulty, not easily.

Which one of the following depicts the correct representation of atomic radius r of an atom? Hence ii and iii are the correct representations.

Which of the following statement s about the modern periodic table are incorrect? All the elements in the modern periodic table are arranged on the basis of their increasing atomic number. All the isotopes can be placed at one place in the same group of the periodic table. The element with atomic number 14 is hard and forms acidic oxide and a covalent halide.

To which of the following categories does the element belong? So, it is a non-metal. Non-metal forms acidic oxide and by sharing of electrons with halogen, it forms covalent halide.

Arrange the following elements in the order of their decreasing metallic character Na, Si, Cl, Mg, Al. Metallic character decreases from left to right in a period. On moving in a i period from left to right, the metallic character decreases. Which of the following set of elements is written in order of their increasing metallic character? Which one of the following does not increase while moving down the group of the periodic Class 5 Maths Chapter 6 Question Answer Time table?

The elements X, Y and Z are shown in a portion of periodic table. What would be the representations of ionic forms of X and Z respectively? Non-metals have 4 to 8 electrons in the outermost shell. The electronic configuration of given elements are a i. Rest three elements with atomic- numbers, 3 Li , 12 Mg and 19 K are metals and hence, form basic oxides. Hence, it forms an oxide having molecular formula E 2 O 3.

In other options, valency of E is not 3. The diagram given below shows the position of elements in a portion of the periodic table. Ionic compound is formed between ���. Hence, both of these will form ionic compound, more readily than the other given elements.

Element X forms a chloride with formula, XCl 2 , which is a solid with a high melting point. The element having valency 2 will be present in group 2. Out of the given choices magnesium Mg belongs to group 2. Identify the heavy metal which belongs to same group as the element discussed above.

Arrange the elements, represented by alphabets p, q, r, s and t in the above shown outline of periodic table, in increasing order of their valency.

The diagram given above represents outline of the periodic table. The alphabets p, q, r, s and t represent elements. Which one of the following pairs of alphabets represents elements which consists of same number of shells in their atom? Modern Periodic Table In , Henry Moseley showed that atomic number of an element is a more fundamental property than its atomic mass.

Elements are placed in groups according to the number of valence electrons and placed in periods according to the number of shells present in them. Helium has valence electrons equal to 2, but it is placed in group number 18 because it is a noble gas and has completely filled outermost shell.

X would most likely to be in the same group of the periodic table as a Na b Mg c Al d Si Answer: b Mg Question 3 Which element has a two shells, both of which are completely filled with electrons? Answer: a Neon 2, 8 b Magnesium c Silicon 2, 8, 4 d Boron 2, 3 e Carbon 2, 4 Question 4 a What property do all elements in the same column of the Periodic Table as boron have in common? Ga, Ge, As, Se, Be Solution: Beryllium Question 14 Which of the following statements is not a correct statement about the trends when going from left to right across the periods of the periodic table?

Mg Question 16 Which element has? Carbon 2,4 Question 17 What property do all elements in the same column of the periodic table as fluorine have in common? Anion will be formed by element A Question 20 Nitrogen atomic number 7 and phosphorus atomic number 15 belong to group 15 of the periodic Table.

Because in period 2, there are two shell, K and L Question 2. For e. In the triad of Fe, Co, Ni, all the three elements have a nearly equal atomic mass and thus it does not follow the above law.

The elements belonging to first seven groups have been divided into sub-groups designated as A and B on the basis of similarities. Group VIII consists of nine elements arranged in three triads. There are six periods numbered 1,2,3,4,5 and 6.

For example, Co and Ni. Hydrogen forms similar compounds as Group 1 elements. Hence, it could not be assigned a fixed position in the table.

For example, Cl has two major isotopes � Cl and Cl Mendeleev predicted the discovery of some elements and named them as eka-boron, eka- aluminium and eka-silicon. One of the strengths of Mendeleev, s periodic table was that, when inert gases were discovered they could be placed in a new group without disturbing the existing order. It was assumed by Newlands that only 56 elements existed in nature and no more elements would be discovered in the future More than one element had to be placed in some of the groups; in order to place the elements having similar properties in one group.

But in order to do so, he also put some dissimilar elements in same group. Iron; which has similar property as cobalt and nickel, was placed far from them. Cobalt and nickel were placed in the group with chlorine and fluorine in spite of having different properties. This is due to an increase in nuclear charge which tends to pull the electrons closer to the nucleus and reduces the size of the atom.

Effective nuclear charge increases. Hence tendency to lose electron decreases. Hence tendency to gain electron increases Variation in group Remains same Increases Increases Decreases Decreases Reason New shells are being added as we go down the group. This increases the distance between the outermost electrons and the nucleus so that the atomic size increases in spite of the increase in nuclear charge. Effective nuclear charge decreases Effective nuclear charge decreases.

Metallic Character. Nonmetallic Character. New shells are being added as we go down the group. Effective nuclear charge decreases. Hence tendency to gain electron decreases.
