P.E of an electron in the orbit of an atom is
Correct answer: B. Less than zero. Here's why
- A. Zero
- B. Less than zero. Here's why
- C. Greater than zero
- D. None of these
Explanation
Potential Energy: The potential energy of an electron in an atom is negative. This is because it is attracted to the positively charged nucleus.Zero Potential Energy: An electron would have zero potential energy if it were infinitely far away from the nucleus.Convention: In physics, we often set the potential energy at infinity to be zero. Therefore, the potential energy of an electron bound to an atom is always negative.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
