SUMMARY
The characteristic electric field in an atom can be calculated using the formula E = e/r², where e is the electron charge and r is the radius of the electron's orbit. The radius can be derived from the equation r_n = n²h²/(4π²me²), which incorporates Planck's constant (h), electron mass (m), and electron charge (e). The correct expression for the electric field in terms of these constants is E = π²m²e⁵/(n²ħ⁴). This formula provides the characteristic electric field in statvolts/cm, confirming its relevance in atomic physics.
