Metallic character decreases across a period.

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.
