Summarize the relationship between an electron's energy level and its location in an atom
FromTheMoon [43]

Answer:

The further an electron is from the nucleus. the greater its energy level.

Explanation:

When an electron is close to the nucleus, it is at as low an energy level as it can get.

We must put energy into an electron to pull it away from the attraction of a nucleus.

So, electrons that are further from the nucleus are at higher energy levels.

Veseljchak [2.6K]

Answer:

When a substance gains or loses energy, its <u>temperature</u> or <u>state</u> changes. These two changes do <u>not</u> happen with respect to time; the temperature remains <u>the same</u> until the change of <u>state</u> is complete.

Explanation:

This statement is about energy and change of the state of the matter. By gaining or losing energy, the physical state of the matter can change into one another. Melting, freezing, condensation, evaporation, sublimation, and deposition are the processes that support to change the physical state of the matter. Change in state and change in the matter do not happen at the same time. A substance gains or loses energy to reach a specific temperature and remains constant until the physical change of matter is completed.
