Question

How is E related to a period of elements?

1)E generally increases from right to left.
2)E generally decreases from right to left.
3)E is constant within any given Period.

Answer 1

Answer;

2)E generally decreases from right to left.

Explanation;

• The E or the Electronegativity is related to a period of elements as in increases across the period from right to left.
• The E increases across the period due to the increase in the amount of charge in the nucleus of an atom, which means the nucleus will attract the bonding pair of electrons more strongly.
• As you move down the group the electronegativity will decrease because the number of energy levels increases and thus the outer electrons are very far away from the pull of the nucleus.

Answer 2

E is related to a period of elements by generally decreasing from right to left. The correct answer is 2.
