Answer is: Ne, P, Ga, Rb.
₁₀Ne 1s²2s²2p⁶.
₁₅P 1s²2s²2p⁶3s²3p³.
₃₁Ga 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p¹.
₃₇Rb 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶5s¹.
Neon has smallest number of orbitals because neon has smallest atomic number (ten electrons), rubidium has largest number of orbitals because rubidium has largest atomic number.
