Question

chemistry semester 1 exam on level 25-26
a measure of the ability of an atom in a chemical compound to attract electrons is called ______.

ionization potential

atomic radius

electronegativity

electron configuration

Explanation:

To solve this, we analyze each option:

• Ionization potential: Energy to remove an electron, not attract.
• Atomic radius: Size of an atom, unrelated to electron attraction.
• Electronegativity: Defined as an atom’s ability to attract electrons in a compound.
• Electron configuration: Arrangement of electrons in an atom, not about attraction.

So the correct term is electronegativity.

Answer:

C. electronegativity
