Inside the Element
Protons
Protons have a positive charge.
The number of protons is the same as the number of electrons, and the atomic number.
Electrons
Electrons have a negative charge.
The number of electrons is the same as the number of protons, and the atomic number.
Contains 7 valence electrons.
Neutrons
Neutrons have no charge.
To find the number of neutrons, subtract the atomic number from the atomic mass.
