Question

What is the quantum number set of the ground-state electron that is found in helium (He) but not in hydrogen (H)?

(1, 0, 0, -½)
(1, 0, 1, -½)
(1, 1, 0, -½)
(1, 1, 1, -½)

Answer 1

@Abhisar

Answer 2

i think that is is A. just making sure ;)

Answer 3

Why A ?

Answer 4

Well first you have to always try to find out the electronic configuration then the quantum states one by one
there is two electron in he ok
so its electronic configuration will be -1s^2

Answer 5

it corresponds to
[n,l,mx,ms]=[1,0,0,(−,+)1/2]

Answer 6

and what for hydrogen ?

Answer 7

huh?

Answer 8

1s\(^1\) is for hydrogen, so what will be its quantum numbers ?

Answer 9

either (1, 0, 0, -½) or (1, 0, 0, +½) ... ryt ?

Answer 10

oh yea sorry i can't think straight!

Answer 11

so then it is A??

Answer 12

yes it is !

Answer 13

yayayyayaya thank yah
