1 Isotopes & Ions. What’s in an atom of a given element? An atom has three subatomic particles: Proton = positive (+) charge Neutron = no charge Electron.

Atoms with a charge. Ion: any atom that has a net electric charge; not neutral If the atom is not neutral, then there must be a different number of protons.

Same Element Different Atom- Isotopes All atoms of a particular element are not exactly alike. Some elements have atoms with different masses (isotopes)

 Protons are positive!!!  Protons have a +1 charge  Protons have a mass of 1 amu  Neutrons are neutral!!!  Neutrons have a neutral or no charge 

There is a decrease in ionisation energy as you go down the group. Beryllium to Magnesium.
