Exploring Atomic Structure

I can describe the structure of an atom, including the location and charge of protons, neutrons, and electrons.

• 1

  Atoms are made of three types of tiny particles called protons, electrons, and neutrons.

• 2

  The number of protons in an atom is also called its atomic number, which determines the element.

• 3

  The strong nuclear force between neutrons and protons holds the nucleus together, preventing positively charged protons from pushing each other out of the atom.
