Question

An electron moves from the ground state (n=1) to an excited state (n=5). Is this emission or absorbance? Is the change in energy positive or negative? Describe the relative stability of the electron after the transition.

Answer 1

When an electron transitions from the ground state (n=1) to an excited state (n=5), it is called absorbance. The change in energy is positive. The electron becomes less stable after the transition.

Step-by-step explanation:

When an electron transitions from the ground state (n=1) to an excited state (n=5), it is called absorbance because the electron is absorbing energy to move to a higher energy level. The change in energy is positive because energy is being added to the atom. After the transition, the electron is in a less stable state compared to the ground state, as higher energy levels correspond to less stability.
