Answer 5

'n' can be any number from 1 to some high number that I'm not sure about.
'l' would be every number from 0 to (n-1)
'ml' will be numbers -l to +l.
'me' will be either -1/2 or 1/2.
:3 You can go through these conditions and possibly cross out some of them.

Answer 6

'ms' not 'me', for isospin.

Answer 7

so would it be the first option?

Answer 8

Nope. If you look at the first option, you can immediately rule it out. The number at the end is +1, which is supposed to be number 'ms'. 'ms' can only be 1/2 and -1/2

Answer 9

i know it is not c

Answer 10

Why do you think it's not C?

Answer 11

because -3 is not an i.e. of -3 the i.e of 4

Answer 12

sorry i mean -3 is not an i.e of 4

Answer 13

Err, yeahhh. o.o
n = 4,
So, the only numbers for 'l' can be 0, 1, 2, and 3. No negative numbers. :3

Answer 14

i stuck so with that being said is the answer be b.

Answer 15

.-. You're not following the guidelines for quantum numbers I gave you.

Answer 16

wait huh?

Answer 17

:33 I posted the guidelines to defining quantum numbers above.
...n can only be numbers 1 to something
'l' can only be numbers 0 to (n-1), it depends on number 'n'.
etc.

Answer 18

oh so than it is d. because the first option has a negative number right?

Answer 19

The third option has the negative number. :3

Answer 20

oh yea that what i meant lol sorry so it is the 1st one

Answer 21

;-; I already explained why it's not choice A. The last number is +1, which is the isospin number. It can only be 1/2 and -1/2.

Answer 22

1/2 or -1/2*

Answer 23

oh sorry so is it D

Answer 24

Yesh, it'll be D. :3

Answer 25

yay! Thank you berry much!
