Ion C4+
| Symbol | C4+ |
| Number | 6 |
| Atomic weight | 12.0096000 |
| Latin name | Carboneum |
| English name | Carbon |
Electronic configuration of of Carbon
C: 1s2 2s2 2p2 → C4+:1s22s02p0
Same electronic configuration has an ion of Carbon +4 and H-1, He, Li+1, Be+2, B+3, N+5
The order of filling the shells with electrons of Carbon (C4+): 1s → 2s → 2p → 3s → 3p → 4s → 3d → 4p → 5s → 4d → 5p → 6s → 4f → 5d → 6p → 7s → 5f → 6d → 7p.
On the sub level ‘s’ there might be 2 electrons at most, on ‘p’ - up to 6, on ‘d’ - up to 10 and up to 14 on ‘f’
Carbon has 6 electrons, let's fill electronic layers in described order:
2 electrons on 1s-sub level
Oxidation state of Carbon
Atoms of Carbon in compounds have an oxidation state of 4, 3, 2, 1, -1, -2, -4.
The oxidation state is the conditional charge of an atom in a compound: the bond in a molecule between atoms is based on the sharing of electrons, thus, if the atom’s charge virtually increases, then the oxidation state is negative (electrons carry a negative charge), if the charge decreases, then the oxidation state is positive.
Oxidation state of an ion C4+ = 4

Valence of C4+
Atoms of Carbon in compounds have valence IV, III, II, I.
Valence of Carbon is an ability of an atom C to build chemical bounds. The valence is based on electronic configuration of atom: electrons participated in chemical bounds are known as valence electrons. In general the valence is:
The number of possible chemical bounds with other atoms
The valence has no sign.
Quantum numbers C 4+
Quantum numbers are defined by the last electron in configuration, for an ion C these numbers are N = 1, L = 0, Ml = 1, Ms = -½
