Question

an ion x contains 7 protons 7 neutrons 10 electrons​

Answer 1

The ion is nitrogen.

It has the atomic number 7.

Nitrogen= N³+

Answer 2

Answer:

Its the stable Nitrogen ion

As Atomic no. = No. of protons = No. of electrons

Since N element having Atomic no. = 7 ,

also ,No. of protons =7 ,

and also ,No. of electrons =7,

has the electronic configuration = 2,5.

Thus being a non metal ,on gaining the 3 electrons in its last shell it completes its ionic property with No. of electrons = 10.

And No. of Neutrons is obviously = 7,

as Mass no.= No. of protons + No. of Neutrons

So, Mass no. of Nitrogen = 14

thus, According to formula

14 = 7 +No. of Neutrons

Hence No. of Neutrons = 14-7 =7
