Amiga · Answer 1

Answer is: 5. one pair of electrons and two lone electrons.

Electron configuration for carbon: ₆C 1s² 2s² 2p².

Valence electrons are in 2s and 2p orbitals. There is one pair of electrons in 2s orbital and two lone electrons in 2p orbital with the same electron spin. Carbon is in group 14 of periodic table group.

Adelaide Goodman · Answer 2

The correct answer is 4. four lone electrons. Carbon is an non metal element in group 4 of the periodic table with four outermost electrons. Lewis dot structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that exists in the molecule.
