HOW DO YOU DETERMINE THE NUMBER OF NEUTRONS IN AN ATOM?
MASS NUMBER - ATOMIC NUMBER
AVERAGE ATOMIC MASS
SUM OF ALL ISOTOPE MASSES MULTIPLIED BY %ABUNDANCE
ION
AN ATOM, OR GROUP OF ATOMS, THAT HAS A NET POSITIVE OR NEGATIVE CHARGE
HOW IS CHARGE INDICATED?
WHAT GROUP THE ELEMENT IS LOCATED IN THE PERIODIC TABLE
HOW IS CHARGE DETERMINED?
LOSS OR GAIN OF ELECTRONS = POSITIVE OR NEGATIVE CHARGE
MOLECULAR COMPOUND
HAVE MOLECULAR & EMPIRICAL FORMULAS (EX. H20)

2 OR MORE NONMETALS
IONIC COMPOUND
CONSIST OF A COMBO OF CATIONS & ANIONS

SAME AS EMPIRICAL FORMULA

SUM OF CHARGES = ZERO
MOLECULAR FORMULA
SHOWS THE EXACT NUMBER OF ATOMS OF EACH ELEMENT IN THE SMALLEST UNIT OF A SUBSTANCE
EMPIRICAL FORMULA
SHOWS THE SIMPLEST WHOLE-NUMBER RATIO OF THE ATOMS IN A SUBSTANCE
CATION
ION WITH A POSITIVE CHARGE
ANION
ION WITH A NEGATIVE CHARGE
MONATOMIC ION
CONTAINS ONLY ONE ATOM
POLYATOMIC ION
CONTAINS MORE THAN TWO ATOMS
DIATOMIC MOLECULE
CONTAINS ONLY TWO ATOMS
BINARY COMPOUND
A COMPOUND CONTAINING ONLY TWO ELEMENTS
TERTIARY COMPOUND
A COMPOUND CONTAINING MORE THAN TWO ELEMENTS; ONE IS USUALLY OXYGEN
ACID
A COMPOUND THAT GIVES OFF HYDROGEN WHEN DISSOLVED IN WATER
BASE
A SUBSTANCE THAT YIELDS HYDROXIDE IONS (OH-) WHEN DISSOLVED IN WATER
THE NAMES OF MANY BASES HAVE WHAT IN COMMON?
CONTAIN HYDROXIDE (OH)
AMMONIA IS CONSIDERED A BASE BECAUSE...
WHEN DISSOLVED IN WATER, IT YIELDS HYDROXIDE
HYDRATE
COMPOUNDS WITH A SPECIFIC NUMBER OF WATER MOLECULES ATTACHED
HOW CAN FORMULAS INDICATE THAT A SUBSTANCE IS HYDRATED?
CONTAIN H20
ANHYDROUS
NO WATER IS PRESENT
