Question

Metallic characters goes on decreasing while going from left to right in period

Answer 1

yes the metallic character decreases from left to right because the nuclear pull increases due to increase in atomic number and atomic size decreases. Hence, elements cannot lose electrons easily. sodium is the most metallic element

Answer 2

1) Metal has the ability to loose an electron.

2) When an electron is added then the size of an atom goes on decreasing due to nuclear pull.

3) Which makes metal more difficult to loose an electron.

4) Hence, metallic characters goes on decreasing while going from left to right in a period.
