Dear King Philip Came Over for Great Sex
Covalent means
share
one element is more electronegative than the other
polar covalent bonds
nonpolar covalent bonds are
symmetric
ionic means
take
bonds that are more like magnetic attractions, atoms not shared, weak
hydrogen bond
order of bond strength
covalent > ionic > hydrogen bond
atoms with the same number of protons but a different number of neutrons
isotope
simple, lack membrane bound nucleus
prokaryotes
have nucleus and organelles
eukaryotes
total mass of an atom; protons + neutrons
, atomic mass
number of protons
