Question

Use the Periodic Table. Choose the correct electron configuration of carbon using the data shown in the electron configuration chart. 1s22s22p1 1s22s22p4 1s22s22p2 1s22s12p2

Answer 1

I think I have done a question like this before and i'm pretty sure your answer would be the 2nd one 1s22s22p4. I'm not 100% sure but try it at least.

Answer 2

electron configuration of carbon: 1s²2s²2p²

Step-by-step explanation:

The electron configuration of atoms (or ions) is depicted based on the Aufbau principle according to which electrons are added to various orbitals such that the orbital with the lowest energy gets occupied first followed by the next higher orbital.

The energy ordering of orbitals from the lowest to the highest is:

1s < 2s < 2p < 3s < 3p < 4s < 3d ....

s orbitals can accommodate a maximum of 2 electrons

p orbitals = 6 electrons

d orbitals = 10 electrons

Now, the atomic number of carbon = 6

Since it is neutral, the atomic number = number of electrons = 6

Based on the Aufbau principle the electron configuration of C would be

1s²2s²2p²
