Metallic character goes on decreasing while going from left to right in a period.

Metallic character goes on decreasing while going from left to right in a period because:

⇒ Metals have a tendency to lose their valence electrons to form a cation.

⇒ As we move from left to right, nuclear charge increases with increase in atomic number. This increase the force of attraction of electrons by the nucleus.

⇒ As a result, the tendency of losing electrons goes on decreasing.

⇒ Thus, metallic character decreases within a period.
