Atoms - the smallest unit of an element Each element is made up of only one type of atom (the element Carbon is only made up of carbon atoms). Atoms are so small they ...

Atoms are the building blocks of elements. They are made up of three subatomic particles: 1) protons are found in the nucleus and have a positive charge.

ATOMS Basic building blocks of matter. Atoms make up everything (that has mass and takes up space).
