Question

Fill in the following blanks using larger or smaller, more metallic or less metallic. Na has a $\_\_\_\_\_\_\_$atomic size and is$\_\_\_\_\_\_\_\_$ than P.

Short answer

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

Step-by-step solution

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.

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 $1^{st}$group and P is in ${15}^{th}$group,

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