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 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 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 radius becomes one and a half times larger
The covalent radius of phosphorus is 100 pm.
The circle becomes an oval
it gets bigger!
Phosphorus (1.23 Å) has an atomic radius smaller than that of tellurium (1.42 Å).
The volume becomes eight-fold.
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.
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.
The volume becomes one eighth.
The area becomes 16 times as much as it used to be.
