1 Atomic structure & Isotopes

• Atoms are made up of protons, electrons and neutrons

• Neutral atoms have the same number of protons and electrons

• You can work out numbers of protons, electrons and neutrons from the element symbol

• To find the total number of electrons for positive ions take away the same number of electrons

from the atom (e g 3 from a 3+ ion) and for negative ions add the same number of electrons
