explain the formation of
magnesium chloride with the help of electron dot structure ​

Answer 1

$\huge{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

The electronic configuration of Mg is 2,8,2. Hence, magnesium needs to loose 2 electrons to become stable. Electronic configuration of chlorine is 2,8,7. Hence, chlorine needs to gain 1 electron to become stable.

Answer 2

The electronic configuration of Mg is 2,8,2. Hence, magnesium needs to loose 2 electrons to become stable. Electronic configuration of chlorine is 2,8,7. Hence, chlorine needs to gain 1 electron to become stable.
