Just as a brief tidbit, you may come across the word "sessile," which is synonymous to "non-motile."

I would presume that we would have to observe atoms without the aid of any microscoping instrument. There have been many models of the atom throughout the centuries, and our idea of the electron shell and the nucleus may not hold in the next 500 years.

This may be the case, though I'll have to recheck my Lewis structures and make sure that there isn't an overall charge of the compound.

I'm not sure with this forum provider, but I know there are some where you can make the spoiler equal to a string and it'll say whatever it wants you to say.

So I'm doing structural chemistry right now, and a few weeks ago we started on Lewis structures. We learned about how the atoms bond to each other with their valence electrons and form octets and that proper Lewis structures have minimized formal charges. What I don't understand are bonding rules. Now most times one electron from atom A is shared with one electron from atom B to form a single bond. But there are times where two atoms from atom A form a bond between it and some other atom. Why is this? Example: Oxygen has six valence electrons. When it has a single bond and completes its octet, it has one single bond and six valence electrons. Why is it like this?

Hey guys, I'm Seiryuu. I'm a first-year student in university, dabbling in biological sciences and well, hope you guys will be able to help me and vice-versa!
