how many valence electrons does carbon atom have?
86210
Four covalent bonds. Carbon has four valence electrons and here a valence of four. Each hydrogen atom has one valence electron and is univalent.

As an example, let's use carbon tetrachloride, CCl4. The single carbon atom contains four valence electrons, and each of the four chlorine atoms contains seven valence electrons. Therefore, the number of valence electrons for this molecule is 4 + (4 × 7) = 32.

The total number of "shared" electrons equals eight, filling carbon's valence shell. The nitrogen's "shared electron" count is six, which means that it needs two more electrons to fill its shell which is accounted for by the lone pair.

Explanation: Take ethylene H2C=CH2 ; around each carbon atom there are 4 valence electrons. Two of these electrons combine with 2 hydrogen atoms (each with 1 electron) to form 2×C−H bonds. Each carbon now has 2 electrons to play with.
