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 an atom of phosphorus becomes a phosphide ion p3 the radius?

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.


When an atom of phosphorus becomes a phosphide ion P-3 the radius increaed Why?

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.

When an atom becomes a cation what happens to its of electrons and its overall radius When at atom becomes an anion what happens to its of electrons and its overall radius?

When an atom becomes a cation, it loses one or more electrons, resulting in a positive charge and a decrease in its overall radius due to reduced electron-electron repulsion. Conversely, when an atom becomes an anion, it gains one or more electrons, leading to a negative charge and an increase in its overall radius due to increased electron-electron repulsion.


Does phosphorus have a larger radius than chlorine?

No, chlorine has a larger atomic radius than phosphorus. Atomic radius decreases as you move from left to right across a period in the periodic table, and phosphorus is to the left of chlorine in the periodic table.
