Discuss the trends variation of metallic and non metallic character in period and group |
|
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 increasesIn group : As ionisation enthalpy decreases down the group, tendency to LOSE valence electrons increase. Hence, metallic character increases and nonmetallic character decreases. |
