bound atoms vs separate atoms
From lecture, Lavelle said that chemical bonds form because bound atoms have lower energy that separate atoms. Could someone explain to me why it's that way?

Re: bound atoms vs separate atoms
I think you can think the problem in this way, with the forming of chemical bonds, more electrons are fixed instead of moving freely. So there will be a decrease in energy for a bound atom compared to the separate ones.
Re: bound atoms vs separate atoms
Bound atoms are more stable because they have a lower potential energy. If atoms are freely moving, they have a greater potential energy and thus are less stable.

Also, bound atoms often take on formations that fill up their orbitals through the octet guideline. This pairs up electrons and keeps them localised around the atom or molecule which keeps them at lower energy.

Re: bound atoms vs separate atoms
Free moving atoms tend to be more unstable because they have a higher potential energy. As such, bound atoms are more stable because their potential energy is lower.

Re: bound atoms vs separate atoms
Free moving atoms have more potential energy therefore are more unstable. Bound atoms have less potential energy because they are bound, so they are more stable than the free moving atoms.
