Answer:
The correct answer is:
b) Increases
Explanation:
Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond. As one progresses from left to right across a period (horizontal row) on the periodic table, electronegativity generally increases.
This trend occurs because atoms to the right side of the periodic table have a greater number of protons in their nuclei, which results in a stronger positive charge. This increased positive charge attracts electrons more strongly, leading to higher electronegativity values.
Therefore, as you move from left to right across a period on the periodic table, electronegativity tends to increase.
