Question

1.71 x 10-6 nm 5.80 x 10 2 nm 1.72 x 10 nm 3.00x108 rn 3. Which of the following quantum numbers is often designated by the letters s, p, d, f, and g instead of numbers? All of the following statements about the quantum numbers are true except 4. n has the integral values from 1 to o e has values from 1 to 00 me has 20 +1 values me has the values of +e to -f, including zero ms has values of +1/2 and -1/2 5. Which of the following sets of quantum numbers is NOT permissible? n = 1, e=0, mf= 0, m s= +112 n=4,1=0, me = o, m s=+1/2 n-3, 1-2, me = 1,ms=-1/2 n-2, 1-1,me = 1, ms--1/2 n=2, 1-0, me = 1, ms=+1/2

Explanation / Answer

3) b) l

4) b) l has values from 1 to infinity

reason : l can assume the value zero too

5) e

reason :

ml can take values from -l to +l

given l = 0

so

ml = 0

but given that ml = 1

so it is not possible
