Question

Write scientific reasons.
b. Metallic character
goes decreasing while going from left to right in a period.​

Answer 1

Answer:

I hope it's helpful...

Explanation:

b. Metallic character goes on decreasing while going from left to right in a period because the tendency of atoms of the elements to lose electrons(or gain electrons) changes in a period. As we move from left to right in a period, the nuclear charge increases due to gradual increase in the number of protons.

Answer 2

Answer:

This is due to valence shell stability. The ionization energy of the elements within a group generally decreases from top to bottom. This is due to electron shielding.
