Question

4. Metallic property change to non metallic property from left to right in a period. Explain.​

Answer 1

Answer :

• Hence, the tendency of the element to lose electrons decreases. This results in decrease in metallic character. Furthermore, the the tendency of an element to gain electrons increases with increase in effective nuclear charge, so non metallic character increases on moving from left to right in a period.

Answer 2

Metallic character decrease and non-metallic character increases in moving from left to right in a period. It is due to an increase in ionization enthalpy and electron gain enthalpy due to the increase in effective nuclear charge.
