The oxides of phosphorus are covalent. There are no ionic charges.
Phosphorus(III) oxide has the formula P2O3 but it exists as the molecule of P4O6
The formula for Phosphorus(V) Oxide [which has 10 oxygen atoms in a molecule] is P4O10.
Magnesium oxide, or MgO, is an ionic compound: the result of a metal reacting with a non-metal.
The ionic compound Co2O is called cobalt(II) oxide.
Sodium oxide (Na2O) is a compound with an ionic bond, not a polar covalent bond. Ionic bonds are typically considered nonpolar due to the way electrons are shared. Sodium donates one electron to oxygen, creating a bond where sodium has a positive charge and oxygen has a negative charge.
Oxide ions have a charge of -2.
An oxide ion has a charge of 2-.
Generally P3- ion in phosphides (so, charge is -3)
P2S3 is an ionic compound. It is made up of phosphorus and sulfur ions that are held together by ionic bonds, where phosphorus typically forms a 3- charge and sulfur typically forms a 2- charge.
The ionic compound for beryllium oxide is BeO. Beryllium is a metal with a 2+ charge, and oxygen is a non-metal with a 2- charge. When they combine, they form a stable ionic compound with a 1:1 ratio of beryllium to oxygen ions.
The formula for the ionic compound formed by magnesium and phosphorus atoms is Mg3P2. This is because magnesium has a 2+ charge and phosphorus has a 3- charge, so the ratio of ions needed for charge balance is 3:2.
Cu3P is an ionic compound. Copper (Cu) typically forms cations with a charge of +2, while phosphorus (P) forms anions with a charge of -3. In Cu3P, the copper cations and phosphorus anions form an ionic bond due to the transfer of electrons.
Yes, phosphorus can form a +3 oxidation state in ionic compounds by losing three electrons to become a P3+ cation. This is commonly seen in compounds like phosphorus (III) oxide (P2O3) or phosphorus trichloride (PCl3).
Iron (III) Oxide ( or, the older term, Ferric Oxide )
The binary ionic compound for calcium oxide is CaO. It is formed by the combination of calcium (Ca) and oxygen (O) ions, where calcium has a 2+ charge and oxygen has a 2- charge.
The formula for sodium oxide is Na2O. This is because sodium has a +1 charge and oxide has a -2 charge, so you need two sodium atoms to balance out the charge of one oxide ion.
There is no such substance as ai2o3 in chemistry. However, Al2O3 (with a lowercase L, not an i) is an ionic compound.
