Elements are defined by how many protons they have.
Electrons can be added and removed from an atom. Protons cannot.
Positive Charge (cation): more protons than electrons. Subtract electrons.
Negative Charge (anion): more electrons than protons. Add electrons.
CRITERIA:
For each diagram
- Write the number of protons in the center of the atom: 6+ (1 marks)
- Draw in the correct number of electrons, in pairs, when possible. (2 marks)
- Write the symbol of the neutral atom or charge particle: C, F 1-, Al3+ etc. (1
mark)
