We have to determine how many orbitals would exist in the n=1 level, in an alternate universe where the value of ℓ is from 0 to n.
To determine the number of orbitals, we have to first define the quantum numbers:
• principal quantum number (n) → energy level in orbitals and its value could be any positive integer starting from 1.
• angular momentum quantum number (ℓ) → (l) has to be at least 1 less than n, range of values from 0 up to (n-1). In the alternate universe it will be 0 → n.
• magnetic quantum number (mℓ) → range of values from -ℓ to + ℓ.
• spin quantum number (ms) → has two values: +½ and -½.
