How many valence electrons does boron need to be stable?

The Lewis dot model of a molecule is shown. A molecule is shown with atoms arranged in the order HCCH. There are three horizontal lines connecting the two C atoms. The C atom on the left is connected to an H atom by a single horizontal line.
