Well, at least I could understand this link. I’m going to have to review the Atomic properties Menu & Structure & Bonding Menu at another time. Right now, they’re just making my eyes roll back in my head.
It’s interesting that an element can be either a single atom or a molecule, which contains 2 or more of the same atoms, chemically bound together. And, they can’t be broken down into simpler matter physically or chemically.
Then there are compounds, which consist of the atoms of 2 or more elements bound together (always in the same ratio to each other) but that can be broken down into their component parts chemically -but- not physically. Whereas mixtures are 2 or more different elements or compounds that have been physically combined and therefore can be physically separated once again.
Looking at this page, the material doesn’t appear that difficult. But, truly understanding it, is another question. I find myself rereading the class material, but not really absorbing it. Chemistry is hard.
