Chemistry Basics
- Element- substance that cannot be broken down by chemical means. Have specific amounts of protons.
- Atom- smallest possible particle of an element. Makes up everything around you.
- APE- atomic number, protons, electrons = equal BUT electrons can change with chemical reaction
- MAN- mass number MINUS atomic number=neutrons
- ATOMIC NUMBER= THE AMOUNT OF PROTONS AND ELECTRONS
- ATOMIC MASS= PROTONS + NEUTRONS
AMU= Atomic Mass Unit
Proton and Neutron have about the same mass.
Electron has less mass than Proton
1836 electrons=1 proton
Electron has less mass than Proton
1836 electrons=1 proton
