Best Answer

One of the following prefixes:

"mono" equals one;

"di" equals two;

"tri" equals three;

"tetra" equals four;

"penta" equals five;

"hexa" equals six;

"septa" equals seven

"octa" equals eight;

"nono" equals nine;

"deca" equals ten;

"undeca" equals eleven; and

"dodeca" equals twelve.

If the name of the element begins with a vowel, and the last letter of the preix as shown above is "a", the "a" is dropped from the prefix. Example: "pentoxide" instead of "pentaoxide".

For covalent molecules one uses a prefix to indicate the number of each atom. For example SO2 would be sulfur dioxide.

What comes first in naming of covalent bonds?

When naming covalent bonds, you first put down the name of the first element. After that, you use a prefix for indicating the number of the atoms of the anion for which you use a suffix. Example: Carbon dioxide.


How do you differentiate the composition of the chemical names of the elements and the chemical names of the compounds?

For covalent compounds, the subscripts indicate the number of atoms of each element in a molecule. When naming a binary covalent compound, the subscripts become part of the name. CO2 = carbon dioxide CO = carbon monoxide H2O = dihydrogen monoxide (common name water) H2O2 = dihydrogen dioxide (common name hydrogen peroxide SO3 = sulfur trioxide S6O2 = hexasulfur dioxide

Is the charge on a diatomic molecule called the oxidation number?

No. The oxidation number is the charge on the atom of an element, or if the bonding is covalent, what that charge would be if that bonding were ionic. A "molecule" with an electrical charge would be a polyatomic ion, not a molecule.
