# Answer to Question #32106 in Inorganic Chemistry for Bandana

Question #32106

The radial distribution curve of 2s sublevel consists of x nodes, x is _______.

Expert's answer

Number of radial nodes for ns orbitals is n-1, where n - principal quantum number. So, 2s orbital has 2-1=1 radial node.

At a very large distance value of the wave function will tend to zero, but will never reach it - even at a distance of 1 km or 1,000 miles from the nucleus the wave function will have non-zero value. In practice, its value is neglected, but there is no nodal surface: probability of being at a nodal surface is zero.
