Alpha Particle
HE with 4 on top and 2 on bottom
Beta Particle
E with 0 on top and -1 on bottom
Gamma Particle
Y with 0 on top and bottom
Half Life Formula
A=A(1/2)^t/h
Atomic radius
gets bigger going down b/c e- are added and smaller going right b/c strong force pulls tightly together
Ionization
Across is more energy b/c closer to octet—>more energy needed to take from valence, down is less energy b/c more shielding means nucleus holds onto e- —> less energy needed
Electronegativity
Increases as you go right b/c closer to octet —> more likely to accept e-, decreases as go down b/c shielding increases ——> hard to attract e-
Ionic radius
measure of cation and anion, cation dec as go L—>R b/c more force, down inc b/c less force, anion dec L—> b/c less force, inc b/c shielding inc
