Which of the following is false?

Options

A. The angule momentum of an electron due to its spinni9ng is given as `sqrt(s(s + 1))((h)/(2pi))`, where s can take a value of `1//2`
B. The angule momentum of an electron due to its spinni9ng is given as `m_(s)((h)/(2pi))`, where `m_(s)` can take a value of `+1//2`
C. The azinuthal quantum number cannot have negative values
D. The potential energy of an electron in an orbit is twice in magnitude as campaired to its kinetic energy

Answer

B

Explanation

b The expression `m_(1) ((h)/(2pi))` is that of z- component of angular momentum
c. The azimuthal quantum number has the value `0 , 1,2, …..(n - 1)`
d. The expression are
`KE = (1)/(2) mv^(2) =- (1)/(2)(Ze^(2))/((4 pi epsilon_(0))r)`
`PE = - (Ze^(2))/((4 pi epsilon_(0))r)`
