Question

Q1.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

Answer:

Element and it's properties

Explanation:

★ Divalent Cation with 10 electrons and mass number 24

it clearly states that the element is magnesium ( Mg+² ) with +2 charge .

» No. of electrons = 10

» No. nuetrons and protons = Mass number - electrons = 24 - 10 = 14

Atomic number = 12 .
