Question

if the value of E is 78.4 Kcal/mol the serial no of orbit in the hydrogen atom is

Answer 1

The serial number of orbit in the hydrogen atom is 2.

The energy of the hydrogen atom is given by the formula

E=$\frac{313.52[tex]Z^{2}$}{$n^{2}$}[/tex]

Here, Z is the atomic mass of the atom

Plugging the values in the above equation

78.4=$\frac{313.52*1}{n^2}$

n=2

Therefore orbit in the hydrogen atom is 2.
