Question

identify the mg2+ ion where n and p represent the number of neutrons and protons respectively ​

Answer 1

Answer:

neutrons will remain 12 in no. becoz their no. is fixed.. and protons wiill be 6

protons are half the no. of electrons in elementary state ...

Answer 2

Answer:

hi friend, mark my answer brainliest , you didnt provide the images, but u have asked it from ncert examplar

Explanation:

in Mg+2 ion the charge is +2

we know,

no.of electrons = no.of protons - charge of the ion(if any)

so, no.of protons in mg's atoms = 12

so , no.of electron = 12-2 = 10

so , the electronic configuration of mg+2 ion will be 2,8

( IT WONT BE 2,8,2 BECAUSE, HERE THE NO.OF PROTONS IS NOT EQUAL TO NO.OF ELECTRONS)

so , you will get only 2 shells , i.e; K AND L SHELL

so, the no.of neutrons = 12

no.of protons = 12

no.of elctrons = 10

no.of shells = 2

option d, accd. to ncert examplar
