There are six electrons in two shells.In order to stable carbon, it take electrons from nearest noble gas to stable the carbon.It order to stable carbon it gain -4 electrons from the nearest noble gas Neon.
An atom of carbon needs 4 more electrons to complete its valence shell, which can hold a total of 8 electrons. Carbon has 4 valence electrons and tends to form 4 covalent bonds to achieve a full valence shell configuration.
In order to be neutral, carbon needs 14 electrons.
Silicon, like carbon, has four valance electrons, and needs another four to have a stable octet.
Three pairs of electrons.
The strongest and most stable bonds involve carbon (C) to carbon bonds. C in sp, sp2, and sp3 hybridization, that is single, double and triple bonds, are the most stable.

Fluorine needs one more electron to have a stable octet, as it has 7 valence electrons and stable octet configuration is achieved with 8 electrons.
