which of the following is the noble gas notation/shorthand for the element carbon? a) he 2s²2p⁶ b) ne 2s²2p⁶…

Brief Explanations:

Carbon has 6 electrons. Helium has 2 electrons. The noble - gas shorthand starts with the noble gas that comes before the element in the periodic table and then lists the remaining electrons in their orbitals. The noble gas before carbon is helium. The electron configuration of carbon is 1s²2s²2p². In noble - gas shorthand, we use the electron configuration of helium and then list the remaining 4 electrons, which is [He]2s²2p².

Answer:

c) [He]2s²2p²
