Molecular (covalent) compounds composed of two elements nomenclature -
Answer 1) name the more metallic element, adding a Greek prefix if two or
more atoms are present
2) name the more nonmetallic element, adding a greek prefix, changing the ending
to "-ide"
Example:
SO3: sulfur trioxide
N2O4: dinitrogen tetroxide
P4O10: tetraphosphorus decaoxide
Binary acid - Answer acids comprised of hydrogen and one other nonmetallic
element
Molecular (covalent) compounds: binary acid nomenclature - Answer 1) add
the prefix hydro-
2) name the nonmetallic element, changing the ending to "-ic"
3) the word "acid" is added as a second word
, Example:
HF: hydrofluoric acid
HCl: hydrochloric acid
H2S: hydrosulfuric acid
Oxyacids - Answer compounds that cocntain hydrogen, oxygen, and at least
one other element (usually a polyatomic, oxygen-containing ion), and are bonded
in such a way as to impart acidic properties to the compound
Molecular (covalent) compounds: oxyacid nomenclature - Answer 1) start with
the root name of the anion
2) replace "-ate" with "-ic", or "-ite" with "-ous"
3) add acid
Example:
HNO3 (nitrate): nitric acid
HNO3 (nitrite): nitrous acid
H2CO3 (carbonate): carbonic acid
H2SO3 (sulfite): sulfurous acid
Octet rule - Answer the tendency of main group atoms to form enough bonds to
obtain eight valence electrons
What are three exceptions to the octet rule? - Answer Odd electron molecules,
electron-deficient molecules, and hypervalent molecules
