Chem Unit 2

atomic number

atoms of same element with different masses

• 23
• 6.02* 10

radio waves, microwaves, x rays, etc

arranged from a long to short wavelength or low to high frequencies

distance between corresponding points

number of waves that pass a given point at a specific time

minimum quantity of energy that can be lost or gained by atom

emmision of electroms from metal when light is shined on it

...ejecting electrons from the metal, causing electrical current

particle of electromagnetic radiation having zero mass

electron falls to a lower energy level

energy added to atom to move electron from lower to higher energy level

bending of waves

waves overlap

impossible to determine simultaneously the position and velocity of electrons or other particles

electron occupies lowest energy orbital that can recieve it

no more than 2 electrons can occupy the same orbital
