Question

Explain the formation of MgCl2 with the help of electron dot structure.

Answer 1

Answer:

Explanation:

Mg electropositive so becomes cation whereas cl electonegative  becomes an anion.

Answer 2

Answer :

• Magnesium chloride (MgCl₂) is formed by the ionic bond formed between magnesium and chlorine atoms.

• 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.

• Therefore, during the formation of the ionic bond, a single magnesium atom loses two electrons. On the other hand, two chlorine atoms gain one electron each.

• Hence, magnesium atom becomes cation (positively charged ion) and each chlorine atoms become anions (negatively charged ion).

Formation of magnesium chloride:

$:\implies\rm{\underset{\rm{2,8,2}}{Mg}\longrightarrow{}\underset{\rm{2,8}}{Mg^{2+}}+2e^-}$

$\rm{\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\:(Magnesium\:cation)}$

$:\implies\rm{\underset{\rm{2,8,7}}{Cl}+e^-\longrightarrow{}\underset{\rm{2,8,8}}{Cl^-}}$

$\rm{\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\:(Chloride\:anion)}$
