a measure of how strongly atoms attract bonding electrons to themselves the amount of energy required to remove an electron from an atom or molecule a measure of the size of an atom

Answer 1

The terms you're referring to are related to key concepts in chemistry:

1. Electronegativity: This is a measure of how strongly atoms attract bonding electrons to themselves. It indicates an atom's ability to attract shared electrons in a bond.

2. Ionization Energy: This is the amount of energy required to remove an electron from an atom or molecule. It reflects how tightly an atom holds onto its electrons.

3. Atomic Radius: This is a measure of the size of an atom, typically defined as the distance from the nucleus to the outermost electrons.

These concepts are fundamental in understanding chemical bonding and the behavior of elements in reactions.
