When an element from anions, the radius of the ion increases when compared to that of the neutral atom. The same is the true for the element (phosphorus) and its anion (phosphide ion).
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.
Lithium phosphide (Li3P) is composed of lithium (Li) and phosphorus (P) elements. It is a binary compound containing these two elements in a 3:1 ratio.
The molecular formula for ruthenium IV phosphide is RuP. Ruthenium has an oxidation state of +4, represented by the roman numeral IV, and phosphorus has an oxidation state of -3. Therefore, one ruthenium atom combines with one phosphorus atom to form RuP.
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 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).
When phosphorus gains three electrons to become the P-3 ion, it forms a negatively charged ion. This extra electron causes repulsion between the electrons, leading to an increase in the atomic radius of the phosphorus atom.
The formula for cesium phosphide is Cs3P. It is composed of one cesium atom (Cs) for every phosphorus atom (P) in the compound.
An atom of Phosphorus with three extra electrons
The formula for gold phosphide is AuP. It consists of one gold (Au) atom and one phosphorus (P) atom.
The covalent radius of phosphorus is 100 pm.
The formula for boron phosphide is BP. It consists of one boron atom and one phosphorus atom, which combine in a 1:1 ratio.
Li3P is the chemical formula for lithium phosphide. It is an inorganic compound made up of lithium and phosphorus atoms, with three lithium atoms bonding to one phosphorus atom. Li3P is a solid material that is typically used in the production of semiconductors and as a precursor for other phosphorus-containing compounds.
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.
Lithium phosphide (Li3P) is composed of lithium (Li) and phosphorus (P) elements. It is a binary compound containing these two elements in a 3:1 ratio.
The chemical formula for titanium (III) phosphide is Ti3P. It consists of three titanium atoms bonded to one phosphorus atom.
The molecular formula for ruthenium IV phosphide is RuP. Ruthenium has an oxidation state of +4, represented by the roman numeral IV, and phosphorus has an oxidation state of -3. Therefore, one ruthenium atom combines with one phosphorus atom to form RuP.
