WebFigure 1: Covalent bond of methane (Source: Self-created) 9 represents fluorine. Mostly halogen. This element has the highest electronegativity and reactivity. Fluorine's atomic number indicates its nucleus' protons and neutrons. Fluorine's "unified atomic mass" is 18 u. (Cui et al., 2024). The nucleon number of fluorine is 19. Methane is a tetrahedral molecule with four equivalent C–H bonds. Its electronic structure is described by four bonding molecular orbitals (MOs) resulting from the overlap of the valence orbitals on C and H. The lowest-energy MO is the result of the overlap of the 2s orbital on carbon with the in-phase … Meer weergeven Methane is a chemical compound with the chemical formula CH4 (one carbon atom bonded to four hydrogen atoms).
