Question

Explain formation of nacl and mgcl2,Al2O3

Answer 1

Answer:

Lewis structure of MgCl2 is shown in image 1.

MgCl2:12Mg2+(2,8)

                 17Cl−(2,8,8)

Lewis structure of Al2O3 is shown in image 2.

Al2O3:13Al3+(2,8)

               8O2−(2,8,8)

Lewis structure doesn't include charge on cation and anion.

Hence, the correct option is A.



Answer 2

Answer:

NACL :- Sodium chloride is formed when sodium atoms interact with chlorine atoms. When this occurs, sodium will donate an electron (which is a negatively-charged particle) to chlorine. This makes sodium slightly positive and chlorine slightly negative.

MGCL12:- MgCl2 formed by the transfer of electrons as Mg have its valency +2 and chlorine has its valency -1 so the product form is MgCl2. solution ofmagnesium chloride conduct electricity because it has H+ ions in the solution as MgCl2 is dissolved in H2O to form solution of magnesium chloride.

AI203:- In terms of electron arrangement in the formation of the ionic compoundaluminium oxide, two aluminium atoms donate their three outer electrons to three oxygen atoms. This results in two triple positive aluminium ions to three double negative oxide ions via electron transfer.
