The types and number of orbitals belonging from the fifth orbit are, respectively, — Atomic Structure Chemistry Question

💡 Solution & Explanation

For a given principal quantum number $n$, there are $n$ types of subshells (s, p, d, f, g for $n=5$), and the total number of orbitals is given by $n^2 = 5^2 = 25$. Therefore, correct answer is A.
