Need help understanding atoms

[metfan]

I just want to check my work and make sure I 'got' it. There are quite a few questions on my homework like these and I don't want to get them all wrong....I need to know how many electrons are in the following atoms: Na+. I say 10 because to make the ion positively charged, 1 electron (which is negative) must be lost. This leaves one extra positeve protron. Na has 11 electrons in its natural state, minus one to make it Na+. This leaves 10 electrons. Am I right?

How about S-2. I say 18. S has 16 electrons originally. Add 2 to make it negative (-2). This makes it 18 electrons.

Do I have it right? It is so confusing. Thanks so much. If it was just one or two questions I would not worry. It is one of those if I have one wrong, I have them all wrong.

Yup! You're right.

I was a Chem major, so your question just made my day!

Happy Chemistry studying!

Yes. Chem major here too you have it right! Good job!

Wow, the way you worded that has cleared up and made sense out of what I have always just taken at face value. You made it all make sense for me. THANKS!

I read this a few days ago and had no clue what you were talking about. I went to class on Wednesday and now I know exactly what you are saying. I am actually learning something. AMAZING.
