Asked by spmtn_dltrn

Methane (CH4) is a gas that is found in small quantities in Earth’s atmosphere. Are the bonds in methane ionic or covalent according to their electronegativities, and how can one carbon atom bond with four hydrogen atoms based on their valence electrons? In three to four sentences, explain your answer. Please make your answer simple, coherent, and intended for 9th grade.

The bonds in methane are covalent because carbon and hydrogen have similar electronegativities (about 2.5 for C and 2.1 for H), so they share electrons instead of one atom taking electrons from the other. Carbon has four valence electrons and needs four more to reach a full outer shell, while each hydrogen has one electron and needs one more. By sharing one electron with each of four hydrogens, carbon forms four single covalent C–H bonds, giving carbon an octet and each hydrogen a full duet.
