Are atoms and molecules the same things?

Answer 1

I am out of my turf here but I would say no.

As far as I can recall, atoms combine to form molecules, like water, which is composed of two hydrogen atoms and one oxygen atom.

A molecule is made up of atoms, sometimes of different types but all with the same structure (varying in number of protons and electrons), whereas an atom has a "fixed" structure of nucleus (protons+neutrons) and electron cloud.

No, atoms and molecules are not the same things. Atoms are the basic building blocks of matter and consist of protons, neutrons, and electrons. Molecules are formed when two or more atoms chemically bond together.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
