Question: What is the primary reason for the high electronegativity of hydrogen compared to alkali metals?

Options:

Correct Answer: It has a small atomic radius

Solution:

Hydrogen has a small atomic radius, which allows it to attract electrons more effectively than larger alkali metals.

What is the primary reason for the high electronegativity of hydrogen compared to alkali metals?

Step 1: Understand what electronegativity means. It is a measure of how strongly an atom can attract electrons.
Step 2: Know that hydrogen is a small atom, meaning it has a small atomic radius.
Step 3: Recognize that smaller atoms can get closer to other atoms, allowing them to attract electrons more effectively.
Step 4: Compare hydrogen to alkali metals, which are larger atoms with a bigger atomic radius.
Step 5: Conclude that because hydrogen is smaller, it can attract electrons better than the larger alkali metals.
