Look at the dots around each symbol and the energy levels from the resources above; Answer the questions in the text entry option for this assignment.
Copy and paste questions and respond in complete sentences.
Include a space between each question.
Be specific with your responses for each question. Assume your reader has no knowledge of the subject and you are teaching them via your answers.
Please answer the following questions:
Why does Na have only one dot?
Why do none of these diagrams show more than 8 dots?
What relationship do you notice between the dots in these two charts?
The number of dots that hydrogen and helium have in their dot diagram is the same as the number of electrons shown for them on the Periodic Table. Why? (Hint: Octet Rule (Links to an external site.))

Hello! Here's the answer I was able to come up with:

Why does Na have only one dot?

Sodium, or Na, has only one valence electron.  (This makes the atom tend to participate in ionic bonding and "give" its single valence electron to an atom like chlorine.)

Why do none of these diagrams show more than 8 dots?

It is physically impossible for an atom to have more than 8 electrons in its valence layer, according to the Octet Rule.

What relationship do you notice between the dots in these two charts?

The dot diagram for each element represents the number of electrons each element will have in its outermost, or valence, shell. (2-8-8)

The number of dots that hydrogen and helium have in their dot diagram is the same as the number of electrons shown for them on the Periodic Table. Why?

An atom can have a maximum of two electrons in its innermost layer. Hydrogen and helium have only one and two electrons, respectively, so they don't have enough electrons to actually have more than one layer. Therefore, their outermost layer is, in fact, their only layer. This is why the number of dots that hydrogen and helium have in their dot diagram is the same as the number of electrons shown for them on the Periodic Table.

Don't copy this word for word! You will most likely be in trouble for plagiarism.  Instead, rewrite these ideas in your own words, or paraphrase. Good luck, and I know you can do it! ♥
