Question 17.

Write scientific reasons.

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


Answer:

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.
