Mn2O3 =
Mn 3+
O 2-
and
MnBr2 =
Mn2+
Br1-
Therefore,
The first binary compound (Mn2O3) contains the ion Mn3+
Mn2P2
One example of a compound that includes a polyatomic ion containing oxygen is sodium nitrate (NaNO3). This compound contains the nitrate ion (NO3-) which is a polyatomic ion that includes oxygen.
The total numbers of positive and negative parts of the compound must be the same. Manganese (IV) has 4 positive charges per ion and phosphate has 3 negative charges per ion; therefore the formula is Mn3(PO4)4.
Sulfuric acid (H2SO4) includes the polyatomic ion sulfate (SO4^2-), which contains oxygen.
An example of a compound that contains both ionic and covalent bonds is ammonium chloride (NH4Cl). In this compound, the bond between the ammonium ion (NH4+) and the chloride ion (Cl-) is ionic, while the bonds within the ammonium ion itself (N–H) are covalent.
The formula for the manganese (III) ion is Mn3+. The charge on the manganese ion is +3.
Mn2P2
One example of a compound that includes a polyatomic ion containing oxygen is sodium nitrate (NaNO3). This compound contains the nitrate ion (NO3-) which is a polyatomic ion that includes oxygen.
PbCO
Polyatomic ion in the compound Na2O2 is known as peroxide. Such polyatomic ion contains two or more atoms covalently bonded.
The formula for manganese (II) phosphide is Mn3P2. This compound is formed by the combination of manganese with a +2 oxidation state and phosphorus.
Lead (IV) ion is found in the compound lead(IV) oxide, which has the chemical formula PbO2.
If the compound contains a polyatomic ion, simply name the ion.
The total numbers of positive and negative parts of the compound must be the same. Manganese (IV) has 4 positive charges per ion and phosphate has 3 negative charges per ion; therefore the formula is Mn3(PO4)4.
Sulfuric acid (H2SO4) includes the polyatomic ion sulfate (SO4^2-), which contains oxygen.
An example of a compound that contains both ionic and covalent bonds is ammonium chloride (NH4Cl). In this compound, the bond between the ammonium ion (NH4+) and the chloride ion (Cl-) is ionic, while the bonds within the ammonium ion itself (N–H) are covalent.
NL3, which represents the compound nitrogen trilithide, is an ionic compound. It contains the nitrogen ion with a -3 charge and the lithium ion with a +1 charge.
