Answer: Carbon’s electron shell configuration is 1s2 2s2 2p2.
Explanation: Electron shell configuration refers to the arrangement of electrons in different energy levels (shells) and subshells of an atom.
For carbon (C) with an atomic number of 6, its electron configuration is as follows:
- The first energy level (K shell) contains the 1s subshell with 2 electrons (1s2).
- The second energy level (L shell) contains the 2s subshell with 2 electrons (2s2) and the 2p subshell with 2 electrons (2p2).
Significance: Knowing carbon’s electron shell configuration is crucial in understanding its chemical properties and reactivity, as well as its ability to form bonds and participate in various chemical reactions.
