B) Calculate the number of atoms of sulfur present in the same sample of SO2

total number of atoms=no.of sulphur atoms+number of oxygen atoms

=1+2=3

can you post a picture of the question I don't really understand what this is asking.

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.

answer: you could do some invislibe ink.

explanation: i will tell you how to if u answer my question.
