For carbon, $Z = 6$ $Z=6$ , and thus its electronic configuration is................

Explanation:

$C : 1 s^{2} 2 s^{2} 2 p^{2}$ $C:1s^(2)2s^(2)2p^2$ . The valence shell of carbon (for which $n = 2$ $n=2$ ) thus contains 4 electrons. Of course there are various hybridization schemes, but the fact remains that carbon commonly forms $C H_{4}$ $CH_4$ and $C R_{4}$ $CR_4$ molecules, i.e. utilizing 4 valence electrons.
