Answer
We are asked to imagine the periodic table if there were no electron spin, but quantum mechanics were otherwise valid.
According to the Pauli exclusion principle, s subshells would hold just one electron (not two), p subshells would hold just three electrons (not six), and d subshells would hold just five electrons (not ten).
