The velocity of the electron moving in the second orbit of He(2+) is equal to 2.18×10^6 m/s.
- The formula for the velocity of an electron moving in the nth orbit of a hydrogen like spiecy is equal to 2.18×10^6×Z/n.
- The above formula is derived by equating the formula of the kinetic energy of a hydrogen like spiecy to mv²/2.
