Write characteristic of s orbitals .

Explanation

For all s-orbitals l = 0 and `m_(1) = 0` but value of n e.g. For is 1s, 2,s 3s, …. Etc the value of n is different but value of l and `m_(1)` is zero.
it is also observed that the size of the orbital increase with increase in n that is
Size 1s `lt 2x lt 3 x lt 4s `
As the value of the increase the distance from attraction with nucleus decreases and electron can easily remove from the orbital

The plane where the value of `w^(2)` is zero and probability to find electron is zero is called nodal plance .
