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".
A subscript number immediately after the atomic symbol.
For covalent molecules one uses a prefix to indicate the number of each atom. For example SO2 would be sulfur dioxide.
A subscript is used.
This is a chemical formula.
Prefixes are used.
A prefix.
A prefix -apex
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.
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.
Formal charge of an atom is the charge assigned to it in a molecule. FC = V - (N + B \2) Where V is the number of valence electrons of the atom in isolation (atom in ground state); N is the number of non-bonding valence electrons on this atom in the molecule; and B is the total number of electrons shared in covalent bonds with other atoms in the molecule. There are two electrons shared per single covalent bond.
The meaning of subscripts in a chemical formula is to indicate the number of a given atom in the molecule.
Prefixes in a name generally indicate the number of atoms of a certain element in a compound. For example, carbon dioxide has two atoms of oxygen and one atom of carbon.

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
The number of atoms of the same element in the molecule
The number of atoms of the same element in the molecule
The number of atoms of the same element in the molecule
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.
Ferric oxide is not a covalent compound, it forms a large ionic lattice.
The number of atoms of that element in the molecule
