ParticlesAtoms and Compounds and Molecules, Oh
My!

(Gas)
One Element (A)
The Same Element (B)(Solid)

This one likes to go round in pairs as a
gas (molecules)
Another element (B)
A mixture of two elements (A and
B)

Compare it to the mixture of two
different elements you drew before
This is a COMPOUND of two different
elements (A and B) (not a mixture!)

What do we call these things?
An Atom
3 Atoms
![Page 20: Particles Atoms and Compounds and Molecules, Oh My!](https://reader035.vdocuments.mx/reader035/viewer/2022070400/56649f115503460f94c23405/html5/thumbnails/20.jpg)
What do we call these things?
6 Atoms which happen to be of 3 different elements
![Page 21: Particles Atoms and Compounds and Molecules, Oh My!](https://reader035.vdocuments.mx/reader035/viewer/2022070400/56649f115503460f94c23405/html5/thumbnails/21.jpg)
What do we call these things?
A Molecule
Yes, it also happens to be 2 atoms joined
together but we don’t call it “2 atoms joined together” we say it is
one molecule
![Page 22: Particles Atoms and Compounds and Molecules, Oh My!](https://reader035.vdocuments.mx/reader035/viewer/2022070400/56649f115503460f94c23405/html5/thumbnails/22.jpg)
What do we call these things?
A Molecule of a compound
2 molecules of a compound
A compound has a definite ratio
of atoms, e.g. H2O is
2 HydrogensTo 1 Oxygen,
always
![Page 23: Particles Atoms and Compounds and Molecules, Oh My!](https://reader035.vdocuments.mx/reader035/viewer/2022070400/56649f115503460f94c23405/html5/thumbnails/23.jpg)
What about when all the atoms are
stuck together like in a solid element?
![Page 24: Particles Atoms and Compounds and Molecules, Oh My!](https://reader035.vdocuments.mx/reader035/viewer/2022070400/56649f115503460f94c23405/html5/thumbnails/24.jpg)
This is just a load of atoms in a solid
element, it is not a big molecule
![Page 25: Particles Atoms and Compounds and Molecules, Oh My!](https://reader035.vdocuments.mx/reader035/viewer/2022070400/56649f115503460f94c23405/html5/thumbnails/25.jpg)
Finally, just to confuse you even more, science teachers like talking
about
ParticlesParticle is just a fancy name for
individual things. These individual things could be atoms, molecules,
lumps of soil, grains of sand, bits of metal. It doesn’t matter because
particle is just a general word which is used when we don’t (or can’t) want to
be exact about the type of things being described.
![Page 26: Particles Atoms and Compounds and Molecules, Oh My!](https://reader035.vdocuments.mx/reader035/viewer/2022070400/56649f115503460f94c23405/html5/thumbnails/26.jpg)
A good example of when science teachers use the word particle is
when talking about air.
Air is a mixture of elements such as oxygen, argon and nitrogen mixed with compounds such as
carbon dioxide
![Page 27: Particles Atoms and Compounds and Molecules, Oh My!](https://reader035.vdocuments.mx/reader035/viewer/2022070400/56649f115503460f94c23405/html5/thumbnails/27.jpg)
Some of the elements in air go around as single atoms (such as
argon).
Or as molecules such as oxygen.
Compounds go around as molecules.
![Page 28: Particles Atoms and Compounds and Molecules, Oh My!](https://reader035.vdocuments.mx/reader035/viewer/2022070400/56649f115503460f94c23405/html5/thumbnails/28.jpg)
That’s why we talk about particles because it saves the bother of describing exactly what sort of
things they are.
