Minimum mumber of nodes are present in

Step-by-step solution

In atomic orbitals, the number of radial nodes is given by the formula n - l - 1 and the number of angular nodes is given by l . The total number of nodes is the sum of radial and angular nodes, which is (n - l - 1) + l = n - 1 . For the 2s orbital, the principal quantum number n = 2 and the azimuthal quantum number l = 0 . Total nodes for 2s = n - 1 = 2 - 1 = 1 . For 3s , n = 3 , total nodes = 3 - 1 = 2 . For 4s , n = 4 , total nodes = 4 - 1 = 3 . For 5s , n = 5 , total nodes = 5 - 1 = 4 . Comparing the values, th
