Short Answer

Expert verified

Na has a larger atomic size and is more metallic than P.

Step by step solution

01

Given Information

We have to find out whether Na has larger atomic size or smaller atomic size than P and also if it is more metallic or less metallic than P.

02

Explanation

Moving left to right in a period, atomic size decreases due to an increase in effective nuclear charge and also metallic property decreases.

Na is in 1stgroup and P is in 15thgroup,

This shows that Na has a larger atomic size than P and it is more metallic than P.
