there is no one answer to this question. It all depends on where the atom is in the Periodic Table.

Each carbon atom has 4 valence electrons. You can find this number on most periodic tables at the top of the row that the element is located in.
a carbon atom has 4 available valence electrons for bonding
Valence electrons are the electrons from the outermost shell of the atom. Number of valence electrons in an atom = the group number of that atom Valence electrons of a moleucle = sum of the valence electrons of all the atoms in that molecule. The molecule HCl has 1 hydrogen (group number =1) and 1 chlorine atom (group number =7). The total number of valence electrons in HCl = 1(1) + 1(7) = 8 Pushpa Padmanabhan Lansing Community College

Formal charge of an atom is the charge assigned to it in a molecule. FC = V - (N + B \2) Where V is the number of valence electrons of the atom in isolation (atom in ground state); N is the number of non-bonding valence electrons on this atom in the molecule; and B is the total number of electrons shared in covalent bonds with other atoms in the molecule. There are two electrons shared per single covalent bond.
nitrogen has 5 valence electrons. carbon has 4 valence electrons.
In an atom the number of electrons is equal to the number of protons. That is, in the case of an un-ionized, non valence bonded molecule... If the atom were ionized, it could have fewer or less electrons. If the atom were part of a valence bonded molecule, it could be sharing valence electrons with other atoms.

There is one lone pair of electrons in a molecule of ammonia: The single nitrogen atom in the molecule has five valence electrons; one of these is in a covalent bond with each of the three hydrogen atoms; and the remaining two valence electrons from the nitrogen atom constitute a lone pair.

This is the valence shell and is involved in bonding e.g. the sharing or loss of electrons to form a molecule or giant structure. Inner shells do not take part in bonding though their shielding effect and repulsion does affect the loss and gain of electrons from this shell.
There are 2 valence electrons in an atom of magnesium. There are 5 valence electrons that are in an atom of phosphorus. There are 4 valence electrons that are in a silicon atom.
The electrons farthest away from the nucleus are the valence electrons of an atom.

the electrons in the outermost shell of an atom are considered to be the valence electrons.
The closer the number of valence electrons is to the number required to completely fill or deplete its outer shell the more likely the atom is to react. With other electrons in an atom the shells are full and they have little if any affect on the reactivity of an atom. Valence electrons are the only electrons that are available to be shared/transferred in a bond.
