Are electrons always shared equally in a covalent bond? Give two examples.

covalent bonds form between two nonmetals, resulting in a sharing of electrons-in order to reach their eight valence electrons (octet rule ) however the atoms rarely share the electrons equally. In polar covalent bonds, the electrons are shared unequally.

ex. HCl

and H2O

h let me think

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.
