Question 247: Atoms & Nuclei

Question

If an electron is moving in the nth orbit of the hydrogen atom, then its velocity (vn) for the nth orbit is given as :

Accepted Answer

We know velocity of electron in n
th
shell of hydrogen atom is given by
$$v = {{2\pi kZ{e^2}} \over {nh}}$$
$$ 	herefore $$ $$v \propto {1 \over n}$$

Answer

$${v_n} \propto {1 \over n}$$

Answer

vn $$ \propto $$ n2

Answer

vn $$ \propto $$ n

Answer

$${v_n} \propto {1 \over {{n^2}}}$$
