ALPHA, BETA & GAMMA RAYS

Moriah Galloway & Kayla SensenigPd. 1 5/14/15

EXPLANATION…

Alpha RaysHas a (+) charge, 2 protons & 2 neutronsWhen the particles are given off, mass number decreasesLosing 2 protons changes atomic number and creates a new elementEx. Uranium (Atomic #- 92) to thorium (Atomic #- 90)

EXPLANATION CONTINUED…

Beta RaysOccurs when(-) charge leaves the electronMore neutrons than protons

Proton stays, electron goes

MORE EXPLANATION…

Gamma RaysWhen given off, no affect on protons & neutrons in nucleusDOES move nucleus energy to a higher state, making it stableEmission occur after:Alpha decay Beta decayNuclear decay
