## 26-3 #2

Use equation 26.8 (Zeeman Effect). This is a simple plug-in calculation.

e = charge of an electron (1.6E-19)

h = Planck's constant (6.6E-34)

B = magnetic field

m = mass of an electron (9.1E-31)

The answer we get is in Joules. Convert this to eV, and that is the final answer.

e = charge of an electron (1.6E-19)

h = Planck's constant (6.6E-34)

B = magnetic field

m = mass of an electron (9.1E-31)

The answer we get is in Joules. Convert this to eV, and that is the final answer.

## 26-3 #3

**l = n-1**

Plug in your given principal number to find l.

Then, as sheet 46' shows, lay out the possible orbital states for all numbers of l, from 0 --> n-1. Then, count the quantum states available in the highest value of l.

So, for example: n=3

l = n-1 = 3-1 = 2

l=0 --> 0

l=1 --> -1, 0, +1

l=2 --> -2, -1, 0, 1, 2

Since l=2 is the highest orbital momentum level, there are 5 states available. That is the answer.

Answer is negative.

## question 2

I have tried several times to plug in the numbers into the equation for number 2 do you think you could post a more detailed explanation of how you did it because I keep getting the wrong answer.

## question 2

I dont understand number 2 either if someone could please explain I would really appreciate that.

Alright. The equation is:

**E = ml * ((e*h*B)/(4*pi*m))**

Now, plug in numbers:

ml = Number given.

e = charge of an electron (1.6E-19)

h = Planck's constant (6.6E-34)

B = magnetic field given

m = mass of an electron (9.1E-31)

Solve, and it gives you the energy in conventional units. Convert this into electron volts (eV). This is the answer.

## having prob with # 1

hey guys, im' having a real problem figuring out how to get # 1

heres the question once again:

The quantum mechanical electron in the hydrogen atom has the orbital (angular momentum) quantum number l = 6. How many quantum states are available to the electron (sheet 45) ? (Disregard electron spin)

## # 1

can someone please explain how to answer question number 1. what are the steps behind the answer?

**physics!**- Guest

## #1

same exact way as #3 if I=4 then ur answer would be 9 because

-4,-3,-2,-1,0,1,2,3,4

answer is positive

-4,-3,-2,-1,0,1,2,3,4

answer is positive

## Q#2, #4

Q#2.

I used the equation given above but I still can't get the right answer. my quantum number m = -3 which equal ml?

Q#4.

I can't get that either. Must not be my day:)

## number 4

i'm pretty sure the answer is to take your n and subtract 1 to get your l. from here, you need to know the structure of an atom, or follow this chart:

0= s = 2 electrons

1= p= 6 "

2= d= 10 "

3= f= 14 "

4= g= 18 "

5= h= 22 "

6= i= 26 "

so my problem:n=4

n-1=1 therefore 4-1=3

follow 3 across on the chart and get 14, which was my answer.

positive.

hope it works for everyone.

## Re: Maple TA 26_3

I still can't get #2

can u guys do ur problems and plug it in

cause i keep getting different answers and all wrong

i converted by dividing the answer by 1.6E-19
