What type of chemical bond involves the sharing of a pair of electrons by two atoms in a molecule.
Over [174]

Answer:

Covalent bond.

Explanation:

There are two kinds of chemical bonds: covalent bonds and ionic bonds.

  • A covalent bond is formed when two atoms share a pair of electrons (two electrons for each bond.)
  • Ions are formed when one atom transfers an electron to another. Ionic bonds refer to the attraction between ions of opposite electric charges.

In this example, since the atoms are sharing atoms, the chemical bond between them would be a covalent bond.
