Atomic Structure

Radioisotopes

Gamma decay(emits radiation with a short wavelength

Beta decay(emits high energy electron)

Alpha decay (release of 2p and 2n)

Periodic Trends

Sheilding

Attraction between valance electrons and nucleus, as well as repulsion between electrons

Group Trends

Electronegativity

Tendency of atom to attract shared electrons when bond is formed

Electron Affinity

Energy released when an electron is attached to a neutral atom

Ionic Radius

Monoatomic ion's radius

Atomic Radius

Distance between center of nucleus and outermost shell of electrons

Ionisation Energy

Least amount of energy it would take to remove most loosely bonded electron
