Question

7. Write scientific reason on :-

Metallic character goes decreasing while going from left to right in a period.

please don't send too long ans. ​

Answer 1

Answer:

As we move from left to right in a period, the nuclear charge increases due to a gradual increase in the number of protons. Due to the increase in nuclear charge, the valence electrons are pulled strongly by the nucleus and it becomes difficult for the atoms to lose electrons. Hence, the metallic character decreases.

Answer 2

Answer:

Metal has the ability to lose an electron. When an electron is added then the size of atom goes decreasing due to nuclear pull which ultimately makes metals difficult to lose electrons. Hence metallic character decreases while going from left to right in a period.

hope it helps you.
