Question

Significance of psi and psi square in quantam mechanics

Answer 1

significance of psi

1)psi is orbital wave function

2)it gives amplitude of electron wave

3)psi takes positive value above the axis and negative value below axis and zero while crossing the axis

significance of psi square

1)it is probability function

2)value of psi square is always positive

3)psi square describes the probability of finding an electron around nucleus around nucleus

4)space around nucleus where psi square is maximum is orbital
