Question

Discuss the trends variation of metallic and non metallic character in period and group

Answer 1

Answer:Metallic character decreases across a period and non metallic increases and metallic character increases down group and non metallic character decreases

Explanation:

Answer 2

Answer:

trends variation of metallic and non metallic character in period and group :

In period : As ionisation enthalpy increases across a period from left to right, the metallic character decreases. Since electron gain enthalpy becomes more negative across a period, nonmetallic character increases

In group : As ionisation enthalpy decreases down the group, tendency to lose valence electrons increase. Hence, metallic character increases and nonmetallic character decreases.
