Metallic character goes on decreasing while going from left to right in a period.
✓
Answer
(i)Metallic character is the tendency of an atom to lose electrons.
(ii) In a period, electrons are added to the same shell and hence, these electrons experience greater pull from the nucleus. As a result outermost shell comes closer to nucleus, atomic size decreases.
(iii) Thus it becomes difficult to remove an electron from the outermost shell of the atom. Hence, metallic character decreases from left to right in a period.
