Concept explainers
(a)
Interpretation: The preferred Lewis symbols of the given elements from the given pair of the Lewis symbols are to be determined.
Concept introduction: The Lewis structure is the representation of a species in which the total valence electrons of the species is show surrounding each atom in the species.
The number of valence electrons is the electrons present in the outermost shell of an element.
To determine: The preferred Lewis symbols of the beryllium from the given pair of the Lewis symbols.
(b)
