(a)
Interpretation:
Lewis symbols for elements with the electronic configuration
Concept Introduction:
Lewis symbol:
A Lewis symbol is a pictorial representation of an elementsurrounded by dots indicating number of electrons in the outer energy level. The group number of the element indicates number of valence electrons.
By using an electron configuration of an atom, we can draw its Lewis symbol by drawing the chemical symbol of the element surrounded by the appropriate number of valence electrons.
