Charges of Subatomic Particles

Recall the specific relative electrical charges of the particles in atoms: Proton (+1), Neutron (0), and Electron (-1).

Understand that in any neutral atom, the number of electrons is exactly equal to the number of protons located in the nucleus, resulting in no overall electrical charge.

Define atomic number strictly as the number of protons contained in an atom of an element.

Understand that all individual atoms of a particular element possess the exact same number of protons.

Explain that atoms of different elements inherently possess different numbers of protons.

Use the standard nuclear model to accurately describe the complete structure of atoms.
