Covalent Bond
Shares outermost electrons
Ionic Bond
exchange electrons
Hydrogen Bond
partially charged hydron attracted to anything with a charge
polar covalent
un-even sharing of electrons (unsymmetrical)
non-polar covalent
even sharing of electrons(symmetrical)
How can an atom be more electronegative than another atom?
Have more protons
What is a buffer?
substances that prevent PH changes
What does the buffer do if the acid is too high?
