Quantum numbers arise naturally from the mathematics used to describe the possible states of an electron in an atom. the four quantum numbers, the principal quantum number the angular momentum quantum number the magnetic quantum number ( and the spin quantum number (ms) have strict rules which govern the possible values. identify all allowable combinations of quantum numbers for an electron. select all that apply. a) =6, =6, =−1, ms=−12 b) =4, =2, =3, ms=+12 c) =2, =1, =0, ms=0 d) ==−1, =0, ms=−12 e) =5, =1, =1, ms=+12 f) =3, =0, =0, ms=+12

e) n=5, l=1, ml=1, ms=+1/2.

f) n=3, l=0, ml=0, ms=+1/2.

Step-by-step explanation:

The 4 quantum numbers are:

Identify all allowable combinations of quantum numbers for an electron. Select all that apply.

a) n=6, l=6, ml=−1, ms=−1/2. NOT ALLOWABLE. When n = 6, l cannot be 6.

b) n=4, l=2, ml=3, ms=+1/2. NOT ALLOWABLE. When l = 2, ml cannot be 3.

c) n=2, l=1, ml=0, ms=0. NOT ALLOWABLE. ms cannot be 0.

d) n=3,l=−1, ml=0, ms=−1/2. NOT ALLOWABLE. l cannot be -1.

e) n=5, l=1, ml=1, ms=+1/2. ALLOWABLE.

f) n=3, l=0, ml=0, ms=+1/2. ALLOWABLE.

answer: 1 2 3 6

step-by-step explanation:

1x6=6 2x3=6

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
