While drawing an electron dot structure, which of the following elements can only have a single bond?

p
o
c
f

F- Fluorine only forms a single bond.
Fluorine has five electrons in its p-orbital. By gaining one electron from the single bond,. Fluorine would then be a stable stony with 8 valence electrons.

Answer:

a. energy is absorbed in the reaction.

explanation:

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
