Question

Electrons with the smallest amount of energy would occupy the principal quantum energy level of:

A) 3
B) 4
C) 5
D) 6

Answer 1

Electrons with the smallest amount of energy would occupy the principal quantum energy level with the lowest value of n. In this case, the principal quantum energy level would be level 1, corresponding to option A) 3.

Step-by-step explanation:

In the quantum-mechanical model of an atom, the state of an electron is described by four quantum numbers. The principal quantum number (n) largely determines the energy of an electron and the electron's position in the atom. Electrons with the smallest amount of energy would occupy the principal quantum energy level with the lowest value of n. In this case, the principal quantum energy level would be level 1, corresponding to option A) 3.
