I've just come across the spin states of a two electron system. There are 4 states possible and I am a little confused as to why the state below has values of s=1 m_s=0?
[1/√2]{α(1)β(2)+α(2)β(1)}
where α(i) and β(i) tell us if the particle has +ve or -ve z component of spin respectively.
I don't quite understand why s=1 as the sum of the spins for this would be (+1/2)(-1/2)+(+1/2)(-1/2)
