1.	Are you familiar with the Bohr model of an atom? See the Bohr model of atoms of certain elements, in group I.(i) Which among them is the biggest?(ii) Which one is the smallest?(iii) What happens to the size of an atom when we move down the group?(iv) What is the reason for this?
Answer» i. Potassium (K) ii. Hydrogen [H] iii. Increases iv. Number of shells increases. As we move from top to bottom of a group in the periodic table the size of the atom increases as there is an increase in the number of shells.

Answer»

i. Potassium (K)

ii. Hydrogen [H]

iii. Increases

iv. Number of shells increases.

As we move from top to bottom of a group in the periodic table the size of the atom increases as there is an increase in the number of shells.
