Question

Show the electronic transfer in the formation of MgCl2 form its elements.

Answer 1

Answer: FIRSTLY,THE ATOMIC NUMBER OF MAGNESIUM (Mg) IS 10 AND THE ATOMIC NUMBER OF CHLORINE (Cl) is 17. Therefore,the when following the octete rule in chemistry wher e the valence shell should have 8 eletrons . So,the electrons have been removed from the mg and transfered to chlorine . hence , it becomes MgCl2.  

Explanation:

Answer 2

Formation of MgCl2

Explanation:

Mg, atomic number 12.

Electronic configuration is 2,8,2.

Octet would be 2.8.

So Magnesium can lose 2 electrons to form the octet.

Valency = +2

Cl, atomic number 17.

Electronic configuration is 2,8,7.

Octet would be 2,8,8.

Chlorine can attract one electron to complete the octet.

Valency = -1

Magnesium ion is formed by donating two electrons.

Mg (2,8) → Mg+2 + 2e-

Chlorine ion is formed by accepting one electron.

Cl(2,8,7) + e- → Cl-

When 2 free chlorine atoms accept the electrons given by single magnesium ion, the compound MgCl2 is formed.
