Question

The atomic radius increases as we move down a group because (A) Effective nuclear charge increases (B) Atomic mass increases (C) Additive electrons are accommodatedin new electron level (D) Atomic number increases

Tardigrade Admin · Accepted Answer

As we move down a group, additive electrons occupy new energy levels and therefore, atomic radius increases

Q. The atomic radius increases as we move down a group because

Effective nuclear charge increases

Atomic mass increases

Additive electrons are accommodatedin new electron level

Atomic number increases

As we move down a group, additive electrons occupy new energy levels and therefore, atomic radius increases
