Question

the first potential of a given atoms is 10.2 volt then ionisation potential must be?(for H like atoms) ​

Answer 1

Answer:

Explanation:

The minimum energy needed to ionize an atom is called ionization energy. The potential difference through which an electron should be accelerated to acquire this much energy is called ionization potential.                

(E2)H−(E1)H=10.2eV     or       (E1)H4−(E1)H=10.2eV ∴  (E1)H=−13.6eV

Hence, ionization potential energy is    =   (E∞)H−(E1)H=13.6eV

∴ lonisational potential=13.6eV
