An ion M3+ has 10 electrons and 14 neutrons

What is the atomic number and Mass number of M???

(please explain in detail)

As the ion m3+ have valency of +3,that means it has 3 protons more than electrons.Therefore, atomic no.=10+3=13mass no.=13+14=27.

atomic number =13

mass number=13+14=27

M3+ is a cation(positively charged) with plus 3 charges

therefor it implies that the number of protons are more than the number of electron.

therefore the no. of p+ are 10 and e- are 7.

the mass no. is = the no. of neutrons+the no.of protons

14+10=24.
