Statement-1: When hydrogen atom is raised from the ground state to an excited state the kinetic energy increases.
Statement-2: The velocity of electron in a quantum state is inversely proportional to the quantum number of the state.
Statement-2: The velocity of electron in a quantum state is inversely proportional to the quantum number of the state.
View answer and explanation
Correct option: D
Statement-1 is false, Statement-2 is true
Statement-1 is false because when a hydrogen atom is raised to an excited state, the kinetic energy decreases. Statement-2 is true because the velocity of an electron is inversely proportional to the principal quantum number.
