Phosphate is H3PO4 and phosphite is H3PO3. Phosphoric acid, when neutralized with a base, such as ammonium or potassium, forms a salt (Phosphate). Phosphorous acid also forms a salt when neutralized with a base (Phosphite). Thus, Phosphite has one less oxygen molecule than Phosphate.
The formula for magnesium phosphide is Mg3P2. It is made of magnesium (Mg) and phosphorous (P). Magnesium phosphide is a white crystalline solid that is toxic by ingestion; it is used to make other chemicals.
The formula for gold phosphide is AuP. It consists of one gold (Au) atom and one phosphorus (P) atom.
The formula for boron phosphide is BP. It consists of one boron atom and one phosphorus atom, which combine in a 1:1 ratio.
Potassium is K (with a 1+ valence) and the phosphate anion is PO4 (with a 3- valence). Thus, it takes 3 K's for each PO4. The formula for potassium phosphate is K3PO4.
When an atom of phosphorus gains three electrons to become a phosphide ion (P3-), it will have a larger radius compared to the neutral phosphorus atom. This is because the additional electrons will occupy outer electron shells, leading to increased electron-electron repulsion and the expansion of the ionic radius.
K3P, three atoms of Potassium and one atom of phosphorous.
The radius of any anion is larger than the original neutral atom. So phosphide (P^3-) which as gained 3 electrons, has a larger radius than phosphorous (P).
The formula for magnesium phosphide is Mg3P2. It is made of magnesium (Mg) and phosphorous (P). Magnesium phosphide is a white crystalline solid that is toxic by ingestion; it is used to make other chemicals.
The chemical compound for Cu3P is copper phosphide. It is composed of three copper (Cu) atoms and one phosphorus (P) atom.
The formula for cesium phosphide is Cs3P. It is composed of one cesium atom (Cs) for every phosphorus atom (P) in the compound.
The formula for gold phosphide is AuP. It consists of one gold (Au) atom and one phosphorus (P) atom.
The formula for boron phosphide is BP. It consists of one boron atom and one phosphorus atom, which combine in a 1:1 ratio.

An atom of Phosphorus with three extra electrons
P is the symbol for Phosphorous. Phosphorous can be found on the periodic table, which means it's an atom of an element. Only atoms of elements are shown on the periodic table, which means that every single thing on it is neutral.PO43- is Phosphate; the ion for the atom phosphorous. It contains 4 oxygen atoms and one phosphorous atom. It's charge is 3- because it is in group 5;this means it has 3 empty spaces for electrons to fill, and hence needs another 3 electrons before it can become a neutral atom again.So the main chemical difference is that one is an atom with a neutral charge, while the other is an ion with a 3- charge.
The chemical formula of potassium phosphide is K3P. It is composed of one potassium atom (K) and one phosphorus atom (P) combined in a 1:1 ratio.
