|
isotops
|
different number of nerutrons, differnt atomic mass but same atomic number
|
|
|
valence electrons
|
most energetic and farthest away from nucleus. defines the chemical properties and reacitvitly of an element
even is isotops, they are the same some diff isotops can substitute |
|
|
molecule
|
2 mor more stable particles joined strongly together.
|
|
|
cimplest formula
|
smallest whole number ratio compound
|
|
|
structural compound
|
tells u most info, structure of how a compound looks like
|
|
|
molecular formula
|
actual number of atoms in each compound. molecule
|
|
|
molecular mass
|
1 mol of cubstance = avagardro number of molecules
|
|
|
dynamic equalibrium
|
what most chemical formulas theoretically are
|
|
|
covalent bond
|
sharing of electrons between atoms
|
|
|
polar covalent
|
unless same coumpound, all covalent are polar. that means then dont share exactly 50-50 so create partial positive and negative charge
|
|
|
electronegativity
|
measure of atom attractive forces to diff things. oxygen is electronegative
|
|
|
cations and anions
|
stupid question
|
|
|
ionic bond
|
they don't share bond, they give away or take electrons, another dumb question
|
|
|
solven, solute solution
|
liqid, solid, miz
|
|
|
hydrogen bonds
|
bond between H and FON
weak by itself, strong together water held by H- binds form with those of partial negative and partial positive charges |
