A simple way of picturing how the valence electrons of atoms interact using the element's symbol surrounded by dots.

What are Lewis Structures?

400

A reaction in which two elements or ions in two different compounds switch places, each becoming part of the other compound.

What is a Double Displacement Reaction?

400

The substance in our atmosphere that blocks ultraviolet rays from the sun.
