Question

1. describe the trend for electronegativity as you move from left to right within a period on the periodic table. why is this the case?

Explanation:

As you move from left to right within a period on the periodic table, electronegativity increases. This is because the number of protons in the nucleus increases, leading to a greater positive - charge attraction for electrons. At the same time, the number of electron shells remains the same, so the out - er electrons are closer to the nucleus and more strongly attracted.

Answer:

Electronegativity increases from left to right within a period on the periodic table due to an increase in nuclear charge and a constant number of electron shells.
