Question

Total energy of an electron in an atom is ________________ .

• A. less than zero
• B. more than zero
• C. may be less or more than zero
• D. none of the above

Answer 1

The correct option is A less than zero

Energy of an electron is given as: $-\frac{13.6Z^2}{n^2}$eV, where n$=$ energy level and Z $=$atomic number. Therefore, it is always negative.
