,In order for a molecule to be polar what two conditions must be met:
Give this one a try later!
- it must have polar bonds
-the bonds must be arranged such that a separation of charge exists.
Coefficients:

numbers used to balance a chemical equation.
What is the law of Volume relationships?

Law of Combined Volumes:
-When all measurements are made at the same temperature and pressure,
the volumes of gaseous reactants and products are in a small whole-
number ratio.
Ground state:

Seven SI base units of measure for matter:
Give this one a try later!
-length/meter
-mass/kilogram
-time/second
-temp/kelvin
-amount of substance/ mole
-electric current/ Amp (A)
-luminous density/ Candela (cd)
Octet rule Metals:
Give this one a try later!
-lose electrons to take on the electron structure of the previous noble gas.
-in doing so, they form positive ions (Cations)
, How many atoms can be shared in Covalent Bonds?
Give this one a try later!
-can share one, two, or three pair forming these types of bonds:
-single
-double
-triple
Risk-benefit analysis:

estimation called the DQ- desirability quotient
