What happens to the electropositive (metallic) character of elements on moving from left to right across a period of the periodic table?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → It decreases.
An electropositive element is one that loses electrons easily. Across a period, the nuclear charge rises and the atoms become smaller, so the valence electrons are held more tightly and are harder to lose. The electropositive character therefore falls steadily from the metals on the left to the non-metals on the right.
