Question

Refer to changes in properties of elements on moving left to right across a period of the periodic table. For each property, choose the letter corresponding to the correct answer from A, B, C, and D.
The electronegativity :

• A. increases
• B. decreases
• C. remains same
• D. depends on number of valence electrons

Answer 1

The correct option is A increases

Electronegativity increases as you move from left to right across a period on the periodic table. This is because, even though there are the same number of energy levels, there are more positive protons in the nucleus, creating a stronger pull on the negative electrons in the outer shell.

Option A is correct.
