Interpretation:
Lewis dot symbol for the given atoms/ions 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 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.
