Question

Which of the following parameters are not same for all hydrogen like atoms and ions in their state?

• A. Radius of orbit
• B. Speed of electron
• C. Energy of the atom
• D. Orbital angular momentum of electron

Answer 1

Answer: (D)

Orbital angular momentum of electron

As we know,

$r\propto n^2$

$E\propto -\frac{z^2}{n^2}$

$V\propto \frac{z}{n}$

$mur=n{h}^2\pi$

So, independent of $z$ so it will remain same.

So, orbital angular momentum of electron
