Question

does helium have a 3s orbital since hydrogen does but at the ground state it only has 1s

Answer 1

No, helium's orbitals are 1s2 (full shell)

Answer 2

so it doesnt apply to any other attom?

Answer 3

Also hydrogen's maximum orbital state is 1s2 also, it cannot achieve 3s

Answer 4

for an element to have 3s orbitals, you need to look at the 3rd row of the periodic table

Answer 5

during excitation the electron can be excited to the 3s stage?

Answer 6

are we talking about electron suborbitals or energy levels?

Answer 7

the question in the book was true or false 3s hydrogen has a 3s orbital the teacher said the answer is true and it can be 3s in excited stage

Answer 8

then you're talking about energy levels for photons :) not electron suborbitals, in that case yes it's possible.

Answer 9

so would He have a 3s orbital too?

Answer 10

i believe so
