Question

In a period or in a group, the larger the atomic sizes of an element, the --------- metallic is the element​

Answer 1

Answer:

more metallic.

Explanation:

The element becomes more electropositive.

Answer 2

Answer:

Across the period tendency of an atom to attract electrons is increased so their atomic size or ionic radius is decreased hence, it's size decreases and they forms an anion. Due to an increase in nuclear charge it results in a decrease of size of an atom. Hence, the non-metallic character increases across a period.
