Question

For any atom of atomic number z the energy of electron in any given orbit is proportional to

Answer 1

Explanation:

The energy of the electron in an orbit is proportional to its distance from the nucleus. The further the electron is from the nucleus, the more energy it has.

Answer 2

Answer:

For any atom of the atomic number "Z", the energy of an electron in any given orbit is proportional to the square of the atomic number i.e.Z².

Explanation:

The energy of an electron in an orbit is given as,

$E=-R_h(\frac{Z^2}{n^2} )$      (1)

Where,

E=energy of an electron in an orbit

$R_h$=Rydberg constant

Z=atomic number of an element

n=quantum state

By considering $R_h$ and n² as constants we can write equation (1) as,

$E\propto Z^2$       (2)

For any atom of the atomic number "Z", the energy of an electron in any given orbit is proportional to the square of the atomic number i.e.Z².
