Question

Explain about the electro negativity and non-metallic character across the period and down the group.

Answer 1

Eletro negativity α Non-metallic character: 

• As the electronegativity is directly proportional to the non-metallic character, thus across the period, with an increase in electro negativity. the non-metallic character also increases. 
• As we move down the group. decrease in electro negativity is accompanied by a decrease in non-metallic character.
