Draw the electron-dot structure of a methane molecule,

Explanation

Carbon has four valence electrons. To achieve stability, it should follow the octet rule i.e, it should have 8 electrons in its valence shell. Hydrogen has 1 electron in its valence shell and should have 2 electrons in its valence shell to achieve stability. Thus, C shares each of its electrons with one hydrogen covalently to form `CH_4` and achieve a stable form.
