Carbon has 4 electrons in its outer shell. 4H atoms with 1 electron each covalently bond with the C atom to make a stable 8 electron shell on the carbon, and an outer 2 electron shell on each H.
Yhere is no way that C has 5 electrons.

Carbon only has 4 valence electrons, not 5.

Carbon only have four outermost electrons

Methane's formula is CH_4 (_ means subscript)

C has the atomic number 6. 2 electrons, then 4 valence electrons.

H has only 1 electron.

4 (from carbon) + 4 * 1 (4 hydrogen atoms) = 8
CH_4 is not an ionic compound, so there's no 9th electron to worry about.

Carbon has 6 not 5 electrons
what makes you think that methane only has 8 electrons?

think protons - carbon has 6 and they go nowhere
each hydrogen has 1 and they go nowhere
so methane has 10 protons and is electrically neutral so it must have 10 electrons
