Question

The atomic radius increases on moving down a group from top to bottom

• A. True
• B. False

Answer 1

The correct option is A True

1. An atomic radius is half the distance between adjacent atoms of the same element in a molecule.
2. Atomic radius increases as we move from top to bottom in a periodic table group because each step adds a new shell of electrons to the atoms.
3. As the number of shells in the atoms increases gradually the size of atoms also increases.

Hence the given statement is true.
