Electronegativity is a really cool topic in chemistry! Let’s break it down simply.

First, let's talk about how electronegativity changes across the periodic table.

• Going from left to right: Electronegativity goes up. This happens because, as you move across a row, the atoms have more protons. More protons mean a stronger pull on the electrons.

• Going from top to bottom: Electronegativity goes down. When you move down a column, the atoms have more electron layers. This makes it harder for them to pull in more electrons.

So, to sum it up:

• You find higher electronegativity on the top right side of the table.
• Lower electronegativity is on the bottom left side.

Pretty fascinating, right?
