any combination of elements that involves a VI and I element, or a V and II element, some examples being NaS-, LiO-, HO- (water, or H2O, is neutral because the extra H+ balances the charge).
Lead (IV) ion is found in the compound lead(IV) oxide, which has the chemical formula PbO2.
The chemical formula for copper(I) bromide is CuBr. It is a compound that contains one copper ion with a +1 charge and one bromide ion with a -1 charge.
An example of a compound that contains an ion with a 3+ charge is aluminum oxide (Al₂O₃). In this compound, the aluminum ion (Al³⁺) has a +3 charge, while the oxide ion (O²⁻) has a -2 charge. The overall neutral charge of the compound is achieved by combining two aluminum ions with three oxide ions. Other examples include iron(III) chloride (FeCl₃), where the iron ion has a +3 charge.
Calcium hydroxide, Ca(OH)₂, is not considered a polyatomic compound itself, but it contains a polyatomic ion, hydroxide (OH⁻). In this compound, two hydroxide ions are bonded to a calcium ion (Ca²⁺). Therefore, while Ca(OH)₂ is an ionic compound, it includes a polyatomic ion within its structure.
The compound NH4₂Cr₂O7, known as ammonium dichromate, contains two ions: the ammonium ion (NH4⁺) and the dichromate ion (Cr2O7²⁻). Each formula unit of ammonium dichromate consists of two ammonium ions and one dichromate ion, balancing the overall charge of the compound. The ammonium ion carries a +1 charge, while the dichromate ion carries a -2 charge.
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.
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.
PbCO
Mn2O3 =Mn 3+O 2-andMnBr2 =Mn2+Br1-Therefore,The first binary compound (Mn2O3) contains the ion Mn3+
Polyatomic ion in the compound Na2O2 is known as peroxide. Such polyatomic ion contains two or more atoms covalently bonded.
Lead (IV) ion is found in the compound lead(IV) oxide, which has the chemical formula PbO2.
The chemical formula for copper(I) bromide is CuBr. It is a compound that contains one copper ion with a +1 charge and one bromide ion with a -1 charge.
If the compound contains a polyatomic ion, simply name the ion.
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 compound with the chemical formula FO4-1 is called perfluorooxide. It contains fluorine (F) and oxygen (O) atoms with a charge of -1.
An example of a compound that contains an ion with a 3+ charge is aluminum oxide (Al₂O₃). In this compound, the aluminum ion (Al³⁺) has a +3 charge, while the oxide ion (O²⁻) has a -2 charge. The overall neutral charge of the compound is achieved by combining two aluminum ions with three oxide ions. Other examples include iron(III) chloride (FeCl₃), where the iron ion has a +3 charge.
