Answer from: cotyross

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 from: BeautyxQueen

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)

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form( $n_2$ ) .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.
