Explanation:
When an electron in a hydrogen atom makes a transition from an excited state to the ground state, there are changes in its kinetic energy, potential energy, and total energy. Let's analyze each option to determine which one is true.
a) Its kinetic energy increases and its potential and total energies decreases:
This statement is incorrect because when an electron moves from an excited state to the ground state, it loses energy. Therefore, its kinetic energy decreases, not increases. Additionally, its potential energy also decreases because it is closer to the nucleus in the ground state. The total energy of the electron also decreases as a result of this transition.
b) Its kinetic energy decreases, potential energy increases and its total energy remains the same:
This statement is incorrect because the electron loses energy during the transition. Therefore, its kinetic energy decreases instead of remaining the same. Its potential energy does increase because it moves closer to the nucleus, but this increase is not enough to compensate for the decrease in kinetic energy. As a result, the total energy of the electron decreases.
c) Its kinetic and total energies decrease and its potential energy increases:
This statement is incorrect because it states that both the kinetic and total energies decrease. While it is true that the kinetic energy decreases, the total energy of the electron also decreases as a result of the transition. It does not remain the same or decrease further.
d) Its kinetic, potential and total energies decrease:
This statement is correct. When an electron in a hydrogen atom transitions from an excited state to the ground state, it loses energy. Therefore, its kinetic energy decreases as it slows down. Its potential energy increases because it moves closer to the positively charged nucleus. The total energy, which is the sum of kinetic and potential energies, also decreases as a result of this transition.
Therefore, the correct answer is option 'A': Its kinetic energy decreases and its potential and total energies decrease.
