Answer:

A #C=C# bond is composed of 4 electrons.

Explanation:

Consider ethylene, #H_2C=CH_2#. Each hydrogen atom has the one electron available for bonding. Each carbon atom has 4 electrons available for bonding. (The remaining electrons #C, Z=6# are inner core, and are not presumed to be involved in bonding.)

So in a olefin bond #C: + :C# gives the #C=C# junction.
