Atoms are made up of protons nutrons and electrons
Protons determine the atom- when you change the number of protons- you change the atom
Electrons determine the atoms behavior
Positive and negative charges attract
Bonds- when atoms combine
ionic bonds- when one atom gives another atom an electron, but then hangs around due to a difference in charge, forms ions
Covalent bonds- when electrons are shared between two atoms (very strong)
Organic- contains carbon
