Question

for simple molecules we can write the lewis structures by simply pairing up the unpaired electrons on the constituent atoms so that each atom has an octet of electrons about it (or a \duet\ for hydrogen)

the following questions pertain to the procedure used to devise a lewis dot structure:
for more complicated molecules we need know the total number of
contributed by each atom.
valence electrons
protons
isotopes
neutrons

Explanation:

1. For simple molecules, Lewis structures are indeed formed by pairing unpaired electrons to give each atom an octet (duet for hydrogen), so the first - statement is true.
2. When devising a Lewis - Dot Structure for more complicated molecules, we need to know the total number of valence electrons contributed by each atom. Protons, isotopes, and neutrons are not relevant in this context.

Answer:

1. True
2. valence electrons
