protons are equal to?
the atomic number
mass number is;
represents the number of particles in the nucleus and is equal to the number of protons and number of neutrons
The atomic mass of an element
is listed below the symbol of each element on the periodic table and gives the mass of an “average” atom of each element
cations
formed by metals and are positive ions.
nonmetals form

the charge of a cation is equal to its
group number
the charge of a anion is by
subtracting 8 from its group number

A MOLE IS A COLLECTIONS THAT CONTAINS
6.02 X10 (23)
HOW MANY Cu ATOMS ARE IN 0.50 MOLE OF Cu?
6.02 X 10(23) / 1 MOLE = 3.0 X 10(23) Cu ATOMS
AVOGADRO’S NUMBER IS USED TO CONVERT MOLES OF A SUBSTANCE TO
PARTICLES
MOLAR MASS IS?

THE ATOMIC MASS OF AN ELEMENT EXPRESSED IN GRAMS

g/MOLE

EX; Ca 1 MOLES IS 40.1g/MOLE TOTAL MASS IS 40.1g

BOYLES LAW STATE THAT
IF THE PRESSURE INCREASES THEN THE VOLUME DECREASES
IN CHARLE’S LAW
T AND V ARE DIRECTLY RELATED HENCE WHEN THE TEMPERATURE OF A GAS INCREASES, ITS VOLUME INCREASES.
GAY-LUSSAC’S LAW IS
P AND T ARE DIRECTLY RELATED TO THE KELVIN TEMP HENCE WHEN P INCREASES T INCREASES
AVOGADRO’S LAW
(T AND P ARE CONSTANT) EFFECT OF n ON V THE VOLUME OF A GAS IS DIRECTLY RELATED TO THE NUMBER OF MOLES (n) OF GAS
SOLUTE ;
THE SUBSTANCE PRESENT IN LESSER AMOUNT
SOLVENT
THE SUBSTANCE PRESENT IN GREATER AMOUNT
____ IS THE MOST COMMON SOLVENT AND IS A POLAR MOLECULE
WATER
UNSATURATED SOLUTIONS CAN
CONTAIN LESS THAN THE MAXIMUM AMOUNT OF SOLUTE AND CAN DISSOLVE MORE SOLUTE
SATURATED SOLUTIONS CAN
CONTAIN THE MAXIMUM AMOUNT OF SOLUTE THAT CAN DISSOVE AND SOME UNDISSOLVED SOLUTE AT  THE BOTTOM OF THE CONTAINER
MOLARITY (M)

IS THE CONCENTRATION TERM FOR SOLUTIONS.

GIVES THE MOLES OF SOLUTE IN 1L SOLUTION

moles/L

THE pH OF A SOLUTIONS  IS CONSIDERE ACIDIC WHEN
THE VALUES ARE LESS THAN 7
THE pH OF A SOLUTION IS CONSIDERE BASIC WHEN
THE VALUES ARE GREATER THAN 7
OIL IS
