The total energy in the 1st orbit of a hydrogen atom is given by:
Correct answer: A. -me⁴/8ε₀ ²h²
- A. -me⁴/8ε₀ ²h²
- B. -me²/8ε₀ ²h²
- C. -me⁴/8ε₀h²
- D. -me⁴/8ε₀ ²h²n²
Explanation
The total energy of an electron in the nth orbit of a hydrogen atom is given by the formula E = -me⁴ / (8 ε₀² h² n²). For the first orbit, n = 1, which simplifies the expression to -me⁴ / (8 ε₀² h²), shown in option A.

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.
