Question

Calculate the ionization energy of hydrogen atom using Bohr’s theory.

Answer 1

Determine what atom you want to use for calculating the ionization energy. Identify the value of "Z" for the atom using a periodic table. (Another name for the number Z is the atomic number.) The value for Z appears above the symbol for the atom. For example, Z equals 1 for hydrogen.

Decide how many electrons the atom contains. This number is the same as Z unless the atom has already lost some electrons.

Calculate the ionization energy, in units of electron volts, for a one-electron atom by squaring Z and then multiplying that result by 13.6.

so ionisation energy is 13.6V.

Answer 2

First we determine the atom we want to use for calculating the ionization energy. Identify the value of "Z" for the atom using a periodic table called the atomic no. otherwise. The value for Z appears above the symbol for the atom. For example, Z equals 1 for hydrogen.

Decide how many electrons the atom contains. This number is the same as Z unless the atom has already lost some electrons.

Calculate the ionization energy, in units of electron volts, for a one-electron atom by squaring Z and then multiplying it by 13.6.

so ionisation energy is 13.6V.
