Explanation:
The negative sign indicates the bound state of the system. The electron experience an attractive force from the nucleus Always remember a negative potential implies attractive force of the system. In order to take an electron to 1st excited state we need 10.2eV of energy Explanation: En (-13.6/n 2)eV. //For hydrogen atom E1--13.6eV E2--3.4eV Energy required-E2-El-10.2eV
