Ions Flashcards
an atom with a charge
ion
one that is positively charged
cation
one that is negatively charged
anion
atoms react to acquire the stable structure of a noble gas by gaining or losing valence electrons
Octet Rule
outermost energy level that contains electrons
valence shell
normal charge of a sodium ion
1+
normal charge of a fluorine ion
1-
one that has lost one or more electrions
cation
one that has gained one or more electrons
anion
usual number of valence electrons of an ion
8
charge of an atom that has gained two electrons
2-
charge of an atom that has lost two electrons
2+
type of element that forms cations
metal
type of element that forms anions
nonmetal
type of element that forms a negative ion
nonmetal
type of element that forms a positive ion
metal
type of element that gains electrons
nonmetal
type of element that loses electrons
metal
determines ion charge
number of electrons
identifies element
number of protons
reason atoms lose electrons
Octet Rule
reason atoms gain electrons
Octet Rule
ion charge is same as number of valence electrons
metal
ion charge is number of valence electrons minus 8
nonmetal
charge of an ion in group 15
3-
charge of an ion in group 16
2-
charge of an ion in group 17
1-
charge of an ion in group 1
1+
charge of an ion in group 2
2+
charge of an ion in group 3
3+
