Question
The ratio of velocity of the electron in the third and fifth orbit of $\mathrm{Li}^{2+}$ would be :(a) $3: 5$(b) $5: 3$(c) $25: 9$(d) $9 \because 25$
Step 1
Step 1: The velocity of an electron in an orbit is given by the formula $v = \frac{v_0Z}{n}$, where $v_0$ is the velocity in the first orbit of the hydrogen atom, $Z$ is the atomic number, and $n$ is the orbit number. Show more…
