The chemical formula of silver phosphide ia Ag3P. The ion of silver is Ag+.
[Ne]3s^23p^6P3-. P is in group V (group 15 moden periodic table) so gains three electrons, each carrying a 1- charge.
The symbol for phosphide ion is P3-, indicating that it carries a charge of -3.
Phosphorus will form the phosphide (P3-) ion.
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.
Everything in Group 5 except bismuth e.g. nitrogen, phosphorus, arsenic, and occasionally antimony
The formula for the ionic compound formed between silver (Ag) and the phosphate ion (P3-) would be Ag3PO4. This is because the charges of the ions must balance to form a neutral compound.
The charge on the phosphide ion in zinc phosphide is -3, because phosphorus typically forms a -3 charge when it becomes an anion.
[Ne]3s^23p^6P3-. P is in group V (group 15 moden periodic table) so gains three electrons, each carrying a 1- charge.
The chemical formula of silver phosphide ia Ag3P.
The most common charge of phosphorus is -5.
Most probably 10 electrons as a phosphide ion with 3-charge has 8 valence electrons.
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.
Formula: [Ag+]3[P3-]
An ion with 15 protons and 18 electrons has a net charge of +3 since it has 3 more electrons than protons. This ion would be classified as a cation.
P3-
P3- is the most common ion of phosphor. Howver, when combined with other elements such as oxygen, the phosphate ion PO43- is the most common.
Phosphorus generally forms phosphide ion (P3- ion).
