The correct option is option 5 that is 1s²2s²2p³.
Acc to the general electronic configuration of carbon is 1s²2s²2p².
- The carbon is present at the 4th group of periodic table. the atomic number of carbon is 6 that means it contains 6 electrons , 6 protons and 6 neutrons.
- since the carbon have four electron in its last shell so it can formed four bonds to fulfill its octet. to complete the octet the atom must have 8 electron its valence shell and become a neutral atom.
- since carbon can shared their four electron with other atom to formed a compound through the covalent bond.
- But now the carbon contain the one ionic charge that means one extra electron is added to the carbon so the electronic configuration is changed.(As per the question) .
- Now the carbon has 7 electrons in its valence shell.
- the orbital are present inside the subshells and their are four types of orbitals that is S, P , D, F.
- filling of orbital with electron are done acc to the Hund's rule , since the carbon have only seven electron , so the filling start from S orbital(closest to the nucleus) with two electrons than two electrons are filled in 2S orbital and In P orbital (Px, Py, Pz), one electron is filled in 2Px and one electron is filled in 2Py and one electron is filled in 2Pz.
- this way the filling of electron are done,
- the orbitals are arranged acc to the energy level.
generally the carbon contains the six electrons but with ionic charge of 1 , the carbon contains seven electrons and these electrons are filled in the orbitals acc to the Hund's rule.

The correct Option is 5 that is 1s²2s²2p³
The atomic number of carbon is six it means the carbon has six electrons and six protons in its valence shell.
Acc to that the general electronic configuration of carbon is 1s²2s²2p ².
since the carbon has four electron in its last shell so it can share their electron with other atom to formed the compound to complete its octet and become the neutral compound.
The orbitals present in the subshell and to fill the orbitals with electron we follow HUND's RULE.
acc to HUND's rule , every orbital are filled first filled with one electron then filled with second electron so as to make doubly occupied the orbital.
There are fours types of orbitals S,P,D,F.
In the S orbital has capacity to filled only two electrons , 2 S orbital filled 2 electrons The P orbitals has capacity to filled 6 electrons divided into 2px , 2py, 2pz (Each contain two electrons).
Since as per the question one ionic charge are added so the total number of electrons in the carbon is 7 acc to that the electrons are distributed in the orbitals.
1S² = 2 electrons
2S²= 2 electrons
2px = 1 electron
2py= 1 electron
2pz = 1 electron
Generally the carbon contain 6 electron but with ionic charge the total number of electron becomes 7 and the filling of orbital follow the Hund's rule.
