Question

what is the velocity of an electron placed in the third orbit of hydrogen atom in centimetres per second

Answer 1

2.18 × 10^8 (z/n) cm (use this)

Answer 2

» HI RUDHRAA »

2.18 x 10 ^ 8 cm This is the cm of an orbit of hydrogen atom.

A calculation shows that the electron is traveling at about 2,200 kilometers per second. 

That's less than 1% of the speed of light, but it's fast because to go around the Earth in just over 18 seconds.
