SUMMARY
The ground state configuration of helium is characterized by a wavefunction that is the product of two hydrogenic 1s wavefunctions and a spin eigenstate in a singlet state. The space wavefunction is hydrogenic due to the similar potential experienced by the electrons, which is scaled for the presence of two protons in the nucleus. The necessity for an antisymmetric wavefunction arises from the fermionic nature of electrons, leading to the requirement that the spin component must be in a singlet state to satisfy the antisymmetry condition.
