accuracy
How close in agreement a measurement is with the accepted value.

angular momentum quantum number
The subshell designation of an electron that describes the shape of the orbital.

The possible values for a particular energy level are 0 to (n=1).
atom
Basic unit of an element that retains all of the element's chemical properties.
atomic mass (weight)
The weighted average of the isotopes' masses.
Aufbau Principle

atomic number
The number of protons in the atom.

The atomic number defines the element.
Avogadro's Law
The volume of gas increases with the number of moles of gas present at constant temperature and pressure (V or n).
Avogadro's number
NA= 6.022 * 10 to the 23rd power items/mole
Boyle's Law
The volume of a gas (maintained at constant temperature decreases as its pressure increases (P or l/V)
carbohydrates
(or sugars) Have the formula Cx(H2O)y, and serve as the main source of energy for living organisms.
Charles's Law
The volume of a gas (maintained at constant pressure) increases directly with an increase in its Kelvin temperatre (V or T).
