Question

define: electronegativity. explain periodic trends in metallic and nonmetallic character​

Answer 1

Answer:

define:

Electronegativity, symbolized as χ, is the tendency for an atom of a given chemical element to attract shared electrons (or electron density) when forming a chemical bond.

Explanation:

Metallic character refers to the level of reactivity of a metal.

Non-metallic character relates to the tendency to accept electrons during chemical reactions.

Metallic tendency increases going down a group. Non-metallic tendency increases going from left to right across the periodic table.
