The correct answer is D. Are formed when atoms share one or more electrons
Step-by-step explanation:
A covalent bond or molecular bond takes place as atoms share electrons, especially electron pairs that are electrons that are in the same orbital but have different spins. These types of bonds made the atoms involved electronic stable. A common example of this is water which is composed of two atoms of Hydrogen and one of Oxygen that formed covalent bonds. Additionally, different covalent bonds can be formed depending on the orbital of each atom. Considering this, the statement that accurately describes covalent bonds is covalent bonds are formed when atoms share one or more electrons.
