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
