Explain the formation of hydrogen, oxygen and nitrogen molecules.

Question: Explain how hydrogen, oxygen, and nitrogen molecules are formed, including the types of bonds formed and the electron configurations of the atoms involved. Answer: Hydrogen, oxygen, and nitrogen molecules are formed through the sharing of electrons between their respective atoms, creating covalent bonds. Hydrogen atoms form a single covalent bond by sharing one electron pair, oxygen atoms form a double covalent bond by sharing two electron pairs, and nitrogen atoms form a triple covalent bond by sharing three electron pairs. This process allows the atoms to achieve stability in their electron configurations: hydrogen with a 1s^2 configuration, oxygen with a 1s^2 2s^2 2p^6 configuration, and nitrogen with a 1s^2 2s^2 2p^6 configuration.
