Ionization potential of hydrogen atom is Hydrogen atoms in the ground state are excited by monochromatic radiation of photon energy The spectral lines emitted by hydrogen atoms according to Bohr's theory will be. The ionization potential of H-atom is The H-atoms in ground state are excited by mono chromatic radiations of photon energy Then the number of spectral lines emitted by the excited atoms, will be. The ionization energy of hydrogen atom is

In physics and chemistry , ionization energy IE is the minimum energy required to remove the most loosely bound electron of an isolated gaseous atom , positive ion , or molecule. Roughly speaking, the closer the outermost electrons are to the nucleus of the atom , the higher the atom's ionization energy. In physics, ionization energy is usually expressed in electronvolts eV or joules J. Comparison of ionization energies of atoms in the periodic table reveals two periodic trends which follow the rules of Coulombic attraction : [4]. The latter trend results from the outer electron shell being progressively farther from the nucleus, with the addition of one inner shell per row as one moves down the column. For example, the first three ionization energies are defined as follows:. The term ionization potential is an older and obsolete term [6] for ionization energy, [7] because the oldest method of measuring ionization energy was based on ionizing a sample and accelerating the electron removed using an electrostatic potential. The ionization energy of atoms, denoted E i , is measured [8] by finding the minimal energy of light quanta photons or electrons accelerated to a known energy that will kick out the least bound atomic electrons.

Last time, we discussed electromagnetic waves and how light is quantized as photons. We related the energy of a photon to its frequency and wavelength using the Planck-Einstein relation:. Electron volts are also a unit of energy, but they are much smaller than a joule. We can convert between joules and electron volts using. Either one works - double checking how your units work out is a great way to check your answer.

The energies of electrons in molecular orbitals can be observed directly by measuring the ionization energy. This is the energy required to remove an electron, in this case, from a molecule:. Therefore, it requires more energy to remove an electron from the hydrogen molecule than from the hydrogen atom; the electron therefore has a lower energy in the molecule.
