Question

Suppose in an atom electrons are present in three different orbitals 3p, 5d and 5s.

Arrange these electrons in there orbitals in increasing order of effective nuclear charge
​

Answer 1

Answer:

There is only one way in which a sphere (l = 0) can be oriented in space. Orbitals that have polar (l = 1) or cloverleaf (l = 2) shapes, however, can point in different directions. We therefore need a third quantum number, known as the magnetic quantum number (m), to describe the orientation in space of a particular orbital. (It is called the magnetic quantum number because the effect of different orientations of orbitals was first observed in the presence of a magnetic field.)

Answer 2

Answer:

Order or shielding effect is s>p>d>f.

Explanation:

This is because s is near to nucleus, so it will shield more the nuclear charge.

As Z

eff

=Z−shielding constant
