Which one of the following statements is correct ?

1.	Which one of the following statements is correct ?
Answer» 2S ORBITAL is SPHERICAL with two nodal planes The de-Borglie wavelength of a particle of mass .m. and velocity .v. is equal to mv/h The principal quantum NUMBER (n) indicates the SHAPE of the orbital The electronic configuration of PHOSPHORUS is given by [Ne] `3s^2 3p_x^1 , 3p_y^1 p_x^1` Solution :2s nodel planes = 0 , `lambda = h//mv`
