How would you explain chemical bonding concept regarding to atoms​

A single bond between two atoms corresponds to the sharing of one pair of electrons. Two hydrogen atoms can then form a molecule, held together by the shaped pair of electrons. Each H atom now has the Noble gas electron configuration of helium ( He). The pair of shared electrons forms a single covalent bond.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
