How to calculate the ionisation energy of hydrogen atom using bohr's theory?
The ionization energy is the amount of energy (kJ/mol or eV/atom) required for separating the electron from the atom in an unexcited state with its transformation into a positively charged ion. Bohr (Danish scientist) formulated three postulates for hydrogen and hydrogen atoms: the postulate of stationary states, the rule of quantization of orbits, the rule of orbits. According to Bohr's theory, the values of the energy of an atom of hydrogen are: En = 1n2·Z2me48h2E02, n = 1,2,3,... It follows from the formula that the energy states of the atom form a sequence of energy levels that vary depending on the value of n. An integer n defines the energy levels of an atom and is called the principal quantum number. The energy state with n = 1 is the main state. A state with n> 1 is called excited. Emin = E1 = -13.6 eV Emax = E∞ = 0 Ionization of an atom is the separation of an electron from an atom. The ionization energy of an atom of hydrogen is 13.6 eV. Ei = Emax - Emin = 13.6 eV
