Question

Where does the constant term −2.18×10^−18J come from in the equation E =−2.18×10^−18JJ(Z^2)/(n^2) for calculating the energy level of an atom?

Answer 1

The constant term -2.18x10^-18 J in the equation represents the ground-state energy of a hydrogen atom.

Step-by-step explanation:

The constant term -2.18x10-18J in the equation E = -2.18x10-18J(Z2)/(n2) for calculating the energy level of an atom comes from the ground-state energy of a hydrogen atom. This value represents the energy required to remove an electron from the hydrogen atom when it is in its lowest energy state.
