# Atoms

## What are atoms?

Atoms are the building blocks of the Universe! They are the smallest unit of everything. Nothing can get tinier than an atom.

## What makes and atom?

Atoms have 3 parts. Neutrons, protons, and electrons. Neutrons have a neutral charge and are located in the nucleus, protons have a positive charge and are located in the nucleus, and electron have a negative charge and are located in the electron cloud. Electrons circle around the outside of an atom.

## What do atoms do?

Atoms come together to make molecules and elements.

## What's the charge of an atom?

When doing the charge of an atom it is important to remember you add all the charges of neutrons, protons, AND electrons. For example, 0= 6, - = 2, += 3. Since, electrons are NEGATIVE you takeaway from the POSITIVE, protons. So it would be POSITIVE 3 takeaway 2, or, POSITIVE 3 plus NEGATIVE 2. Which would equal the same thing, and since neutrons are neutral or zero, you don't add anything because they equal zero. Ex. 0= 6, - = 2, += 3.

0 + 3 + -2 = 1 is the charge of the atom.
