What is C- electron configuration?

Answer 1

1s22s22p3. Adding the exponents gives a sum of 7, which is the total number of electrons a C- ion has. Follow a diagonal rule chart and they should become easy.

Answer 2

The electron configuration of carbon is 1s^2 2s^2 2p^2, representing the distribution of electrons in its energy levels. This means that carbon has 6 electrons, with 2 in the first energy level and 4 in the second energy level.
