Answer:
Four (4 ) electrons will be in its outermost shell . See the explanation below, please
Explanation:
The Carbon atom has an atomic number (Z) 6, that means it has 6 protons in its nucleus; this being the same number of electrons (6). Its mass number is 12: equivalent to the number of protons plus neutrons. The electronic configuration of Carbon is 1s2 2s2 2p2. In the last energy level it has 4 electrons, needing 4 more to complete the octet (it can share 2 pairs of electrons)
