Question

Compared to a phosphorus atom, a P3- ion has

Answer 1

Compared to a phosphorus atom, a P3- ion has more electrons and a larger radius. With a negative charge means there are more electron than protons, this increases the radius because positive charge is trying to hold a larger negative charge. Hope this helps

Answer 2

Answer:

Three more electrons

Explanation:

Compared to a phosphorous atom (P) the P3- ion has gained 3 electrons resulting in the trivalent negative charge. P3- is a reduced state of P and to name some properties:

• It has a bigger atomic radius due to the extra electrons and the weaker attraction the protons have to them.
• It can react as a base (taking electrons)
