Use the periodic table.
choose the correct electron configuration of carbon using the data shown in the electron configuration chart.

1s 22s 22p1

1s22s22p4

1s 22s 2p2

1s 22s 22p2

The answer to your question is: d

Explanation:

Electron configuration of Carbon.

Atomic number of carbon = 6

a) 1s²2s²2p¹  Number of electrons = 5, This is the electron configuration of Boron.

b) 1s²2s²2p⁴  Number of electrons = 8. This is the electron configuration of oxygen.

c) 1s²2s²p²  Number of electrons = 6. This is the electron configuration of carbon. But I think is lacking a number two before p.

d) 1s²2s²2p² Number of electrons 6, This is the correct electron configuration of carbon.

"the periodic table is arranged in order of atomic number."

your answer would be “dry”
