student help: Discuss the formation of a Barium Ion. - Help.com

An ion is when an atom becomes positive or negatively charged. Atoms by definition are neutral, so when they become + or - they are an ion. It becomes an ion by losing or gaining electrons.

As for Barium, it has two valence electrons, so I guess it becomes a negatively charged Ion.

I helping any at all?

ionic bond is when one gives a electron, one receives one, now one is -, one +, they attract each other and bond.

You would need four Barium atoms to reach an octet, right?

I think so.

I’ve just started learning this stuff in class, odd, as I am in a biology class.

Hmmm… I wonder what that has to do with boilogy… You should ask your teacher.

What grade are you in, Ikari?

Well, we are learning it as part of bio-chemistry…

9th, American Grade system.

You’re learning faster than I was. Are you doing Bio-chem as a part of Integrated Science 9, or is that the whole class?

It’s just one chapter of biology class. We also go into evolution and other stuff.

What do you know about salt compounds?

Nothing at all really.

Gah… curses. Chem is evil.

But without it we’d never have silly putty.

salt is found when reaction between a aside and base for example Na+oH
Na+CL

Na+oH is not wright
