Question

Explain how metallic and non metallic properties of the elements vary in a period of the periodic table with an example

Answer 1

Answer:

Due to this effective nuclear charge increase. More is the effective nuclear charge, more is the attraction between nuclei and electron. Hence, the tendency of the element to lose electrons decreases, this result in decrease in metallic character. Furthermore, the tendency of an element to gain electrons increases with increases in effective nuclear charge, so non-metallic character increases on moving from left to right in a period.
