Current Question (ID: 7562)

Question:

$\text{The correct order of increasing energy of atomic orbital is:}$

Options:

1. $\text{3s, 3p, 4s, 3d, 4p}$
2. $\text{3s, 3p, 3d, 4s, 4p}$
3. $\text{3s, 3p, 4s, 4p, 3d}$
4. $\text{3s, 3p, 3d, 4p, 4s}$

Solution:

$\text{Hint: Use Bohr bury rule.}$\n\n$\text{Explanation:}$\n\n$\text{(i) (n + l) Rule = electron will enter having lesser value of (n+l)}$\n\n$\text{(ii) if (n+l) = same}$\n\n$\text{Electron will enter to the subshell having lesser value of n.}$\n\n$\text{orbitals}\quad\text{n+l}$\n\n$\text{3s = }\quad 3+0=3$\n\n$\text{3P= }\quad 3+1 = 4$\n\n$\text{4s = }\quad 4+0 =4$\n\n$\text{3d = }\quad 3+2 = 5$\n\n$\text{4p = }\quad 4+1 = 5$\n\n$= \text{3s} < \text{3p} < \text{4s} < \text{3d} < \text{4p}$\n\n$\text{So, the option 1 is the correct answer.}$
