(a)
Interpretation: Using Lewis dot symbol the transfer of electrons between the given atoms to form cations and anions has to be shown.
Concept Introduction: Lewis dot symbol is used to represent the valence electrons of an atom or ion using dots surrounding the element symbol along four sides of the element symbol without maintaining exact order for the placement of dots.
In Lewis dot symbol representation, the
The valence electron is the number of electrons present in the outermost shell of the atom. The number of valence electrons will be same for the same group elements which is represented by Lewis dot symbol.

Concept Introduction: Lewis dot symbol is used to represent the valence electrons of an atom or ion using dots surrounding the element symbol along four sides of the element symbol without maintaining exact order for the placement of dots.
In Lewis dot symbol representation, the symbol of element is surrounded by "dots" indicating the number of valence electrons available for the element. The dots can be placed one at a time on all the four sides, further electron can be placed by pairing up with the first placed dots. According to the number of electrons added or removed, charge must be placed on the Lewis dot symbol for cations and anions.
The valence electron is the number of electrons present in the outermost shell of the atom. The number of valence electrons will be same for the same group elements which is represented by Lewis dot symbol.
