First you need to find the number of valence electrons in \(\mathrm{NH}_{2}
\mathrm{Cl}\). For counting purposes with Lewis structures, the number of
valence electrons in an atom of a main group element is equal to the last
digit in the group number of that element in the Periodic Table. \(\mathrm{N}\)
is in Group _____ \(\mathrm{H}\) is in Group _____ Cl is in Group ______ In
\(\mathrm{NH}_{2} \mathrm{Cl}\) there is a total of _______ valence electrons.
