Question

Give Scientific reason


Atomic size increases down the group.​

Answer 1

Answer:

Atomic radius increases as we move from top to bottom in a group of the periodic table because a new shellof electrons are added to the atoms at every step. As the number of shells in the atoms increases gradually due to which thesize of atoms also increases. As the size of the atoms increases which leads to an increase in atomic radius of an atom.

Answer 2

Answer:

Atomic radius increases as we move from top to bottom in a group of the periodic table because a new shell \lof electrons are added to the atoms at every step. ... As the size of the atoms increases which leads to an increase in atomic radius of an atom.
