There are no Oxygen in the Phosphides
The three most common such ions probably are sulfate, with the formula SO4-2, chromate, with the formula CrO4-1, and perchlorate, with the formula ClO4-1.
The ion of phosphorous (P) is P^3- and is referred to as phosphide.
The chemical formula of silver phosphide ia Ag3P. The ion of silver is Ag+.
The radical of phosphide is represented by the symbol P^3-. This means that the phosphide ion has a charge of -3.
P3- This is the phosphide ion, but it is not stable in water, only with 3H in PH3 (comparable with ammonia NH3) or with some metal ions (eg. Li3P, Ca3P2, AlP) it is found as pure substance. There are also other form with negatively charged phosphorous in it.
The formula of the phosphide ion is P3-. This is because in the compound zinc phosphide (Zn3P2), the two phosphide ions (each with a charge of 3-) combine with three zinc ions (each with a charge of 2+) to achieve overall charge neutrality.
The phosphide ion is stable
The three most common such ions probably are sulfate, with the formula SO4-2, chromate, with the formula CrO4-1, and perchlorate, with the formula ClO4-1.
The ionic formula for sodium phosphide is Na3P. This compound consists of three sodium ions (Na+) for every one phosphide ion (P3-), resulting in an overall neutral charge.
K3P is the chemical formula. The name of this compound it potassium phosphide.
The correct formula for phosphate ion is PO4^3. Phosphate carries a negative charge and is the conjugate base of hydrogen.
The ion of phosphorous (P) is P^3- and is referred to as phosphide.
The chemical formula of silver phosphide ia Ag3P. The ion of silver is Ag+.
The charge on the phosphide ion in zinc phosphide is -3, because phosphorus typically forms a -3 charge when it becomes an anion.
Yes, ammonium phosphide is an ionic compound. It is formed from the ionic bonding between the ammonium ion (NH4+) and the phosphide ion (P3-).
Phosphide itself is not much. I think what you mean is the phosphide ION. The formula for phosphorus is P, as you must know, but the phosphide ion is P3- ( the ionic charge being in superscript) And it is so because when bonding, Phosphorus will gain three more electrons to complete its full octet as before bonding, it only has 5 electrons in its valence shell.
The correct ionic formula when Mg^2+ and P^3- react is Mg3P2. The magnesium ion has a charge of 2+ and the phosphide ion has a charge of 3-, so to balance the charges, two magnesium ions are needed for every three phosphide ions.
