Question

Number of electrons taken up by nitrogen atom when a NO* ion is redcued to NH,OH is :
(1)3
(2)2
(3) 4
(4)0​

Answer 1

Answer:

2

Explanation:

To solve such questions, start by calculating the oxidation state of the element for which you need to calculate . Which in this case happens to be Nitrogen.

We see, in the first compound ( NO+) the oxidation state of Nitrogen happens to be in +3 state; i.e. it has 3 more protons than the number of electrons it has.

Whereas in the second case, Nitrogen happens to be in +1 state; implying it has 1 more proton than the electrons.

There fore you can comment that it has taken up 2 electrons.
