Question

the divalent cation of an atom contains 10 electrons .if mass number of an element is 24.find the number of electrons,protons and neutrons in the ion and atomic number of the element.​

Answer 1

Explanation:

divalent cation means it carries +2 charge

it has 10 electrons after becoming cation

mass num 24

in cation

electron 10

proton 12 cz after loosing 2 electrons it carries 10 electron

so initially it has 12 electrons

no. of proton = no. of electron

atomic num 12 Magnesium
