The significance of carbon having four valence electrons is that it has four bonds which allows it a wide combining capacity.

The valence number represents the ability of the element to gain or give up electrons during a chemical reaction or bond.  

Carbon in its electronic configuration shows that there are 4 electrons in its last shell, missing another 4 to complete it due this it tends to share 4 electrons through covalent bonds.

Thanks to this tetravalence, carbon has a wide combining capacity due to its atoms can be linked in complex structures since they have a four-fold chance of establishing bonds.

About the tetravalency of carbon:

  • The tetravalence indicates that an element has four valences: that is, four bonds.
  • These four bonds are located symmetrically in space, going to the lines that link the nucleus of the tetrahedron with its vertices.

Therefore, we can conclude that the significance of carbon having four valence electrons is that it tends to share 4 electrons through covalent bonds which gives it a wide combining capacity.
