Question

In a single carbon bond, two carbon atoms share

A carbon has 4 valence electrons meaning it can share 4 electrons and is in short of 4 electrons to fill it outer energy shell making it 8. Which results to 2 double covalent bonds ,meaning there was a sharing of 2(4) = 8 electrons . Hope this helps . Your statement above is true .
