2. Metallic character decreases across a period.
Ans. 1. Metals have
a tendency to lose electrons and are said to be electro positive.
2.
As we move across a period, the atomic number and the nuclear charge increases.
So, the atomic size decreases.
3.
As a result, electrons are more tightly bound to the nucleus and more amount of
energy is needed to remove an electron from the outermost shell. So, metallic
character decreases across the period.
