15 Cards in this Set

  • Front
  • Back
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
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
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
