The electron in a hydrogen atom has an orbital radius of 0.0500 nm.To avoid being pulled into the nucleus by electrostatic attraction,the electron must have an orbital speed of A)7.12 km/s B)25.2 km/s C)1.02 $\times$ 10⁶ m/s D)2.25 $\times$ 10⁶ m/s E)5.0 $\times$ 10⁸ m/s

Question

Quizplus · Accepted Answer

The orbital speed of an electron in a hydrogen atom can be calculated using the formula for centripetal force, which equates the electrostatic force to the centripetal force: $ v = \sqrt{\frac{k \cdot e^2}{m \cdot r}} $. Substituting the known values gives approximately 2.25 x 10^6 m/s.
