Question

On the basis of the given table are the following question:
i) which element will form cation?
ii) which element will have smallest atomic size?
iii) which element will have chemical properties similar to Magnesium(at. no. 12)?
iv) write the common name of group to which C and E belong? ​

Answer 1

Answer:

i. B element will form cation.

ii.C element will have smallest atomic size

iii. B element will have chemical properties similar to Magnesium(at. no. 12

iv. The common name of group to which C and E belong is Halogen.

Answer 2

1) B will form a cation.

2) C will be having smallest atomic size.

3) Element B have chemical properties similar to Magnesium

4) C and E belong to group 17, Halogens

• We have a representation of modern the periodic table with 7 periods and 18 groups.
• 1) In the periodic table Alkali metals (group 1) and Alkaline Earth metals (group 2) are likely to form cations.
• In the given table B belongs to group 2, and is more likely to form a cation.
• 2) In the periodic table atomic size decreases left to right in the period and  Atomic size increases down the group.
• Considering these two factors element C will have the smallest atomic size.
• 3) Elements belonging to the same group have the same properties.
• Magnesium belongs to group 2, in table B also belongs to group 2.
• Hence B will have properties similar to Magnesium.
• 4) Group 17 is the Halogen group, so C and E belong to the Halogen group.
