Understand that hybridization involves mixing atomic orbitals to form new hybrid orbitals suitable for bonding in molecules.
Recall that the notation sp^n indicates the mixing of one s orbital and n p orbitals, so the total number of orbitals mixed is (1 + n).
Since the problem states that three atomic orbitals are mixed together, set up the equation: 1 (s orbital) + n (p orbitals) = 3 orbitals.
Solve for n: 1 + n = 3, which gives n = 2, meaning two p orbitals are mixed with one s orbital.
Therefore, the hybrid orbitals formed are sp^2 orbitals, which correspond to the mixing of one s and two p orbitals.
