D. Same energy level but different sublevel.
<h3>Explanation</h3>
There are four quantum numbers [1]:
- <em>n</em><em>, </em>the principal quantum number,
- <em>l</em>, the orbital angular momentum quantum number,
- <em>
</em>, the magnetic quantum number, and - <em>
</em>, the electron spin quantum number.
As their names might suggest:
- <em>n </em>determines the main energy level of an electron.
- <em>l</em> determines the type of sublevel of an electron.
- Each sublevel might contain more than one orbital. <em></em> gives the orbital of an electron.
- Each orbital contains up to two electrons. <em></em> tells two electrons in the same orbital apart.<em> </em>
The two electrons in question come from the same atom. The question suggests that they have the same <em>n</em>, <em></em>, and <em></em>. As a result, both electrons are in main energy level <em>n</em> = 3. They share the same spin.
However, the two electrons differ in their value of <em>l</em>.
- <em>l </em>= 2 for the first electron. It belongs to a <em>d</em> sublevel.
- <em>l </em>= 1 for the second electron. It belongs to a <em>p</em> sublevel.

Solar panels transform the energy from the light of the Sun and turns it into electricity.
Answer:
Radio waves are a type of electromagnetic radiation best-known for their use in communication technologies, such as television, mobile phones and radios.
Chemical reaction is the basis of life for living organisms; no organism can remain alive without the occurrence of chemical reactions.
Chemical reactions that occur in the living organisms are called biochemical reactions, these reactions are needed for the organism to grow, develop, survive and remain alive; when the chemical reactions stop the organism die.
For instance, to remain alive one has to eat. The food eaten can not be useful to the body if the digestive enzymes do not carry out chemical reactions on it and convert it to a form that can easily enter the blood where it is needed.
They are living organisms in the ecosystem and make up part of the food chain.<span />
