उत्तर

Orbit Orbital
It is an well defined
circular path around the
nucleus in which electrons
revolve
It is an three dimensional
space around the nucleus
around which the
probability of find the
electron is maximum
It represent planar motion
of electron around the
nucleus
It is the three dimensional
motion around the nucleus
It have circular or disc like
shape
Different orbitals have
different shapes such as s-
orbital spherical shapes.

The arrangement of orbitals on the basis of energy is based upon their (n + l) value. Lower the value of (n + l), lower is the energy. For orbitals having same values of (n + l), the orbital with lower value of n will have lower energy.

Based upon the above information, arrange the following orbitals in the increasing order of energy.

4s, 3s, 3p, 4d
