Question

How do the following properties vary in a given period: a. Atomic size b. Valence Electrons c. Valency d. Metallic & Non Metallic character​

Answer 1

Answer:

Atomic size - Atomic size decreases as we move from left to right in the Periodic Table.

Valence Electrons - The number of valence electrons increases as we move from left to right. However, in a group the number of valence electrons remains the same.

Valency - Valency increases as we move from left to right to some point after which it decreases.

Metallic & Non Metallic character - Metallic character increases down the group and decreases from left to right across the period.
