Discover the total energy of electrons in hydrogen-like atoms with our easy-to-use online calculator. Input the atomic number (Z) and principal quantum number (n) to instantly determine energy levels, crucial for understanding atomic structure and quantum mechanics. Perfect for students and researchers.
Formula:
En = -13.6 × (Z2 / n2) eV
Where:
En = Total energy of the electron in the n-th orbit (in electronvolts, eV)
Z = Atomic number (number of protons, e.g., 1 for H, 2 for He+)
n = Principal quantum number (electron shell level, e.g., 1 for ground state, 2 for first excited state)
