Recall that valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.
Identify the atomic number of carbon, which is 6, meaning a carbon atom has 6 electrons in total.
Determine the electron configuration of carbon in the ground state: \$1s^2 2s^2 2p^2$.
Recognize that the valence electrons are those in the outermost shell, which for carbon is the second shell (the \$2s$ and \$2p$ orbitals).
Count the electrons in the \$2s$ and \$2p$ orbitals: \(2 + 2 = 4\) valence electrons.
