Now let's further get into the periodic elements
and let's talk about the atomic symbols. Capital
H is for hydrogen. Hydrogen peroxide, you
use it around your house. Capital H and lower
case e, He, helium. Very simply a helium balloon.
Remember when you blow a helium balloon and
you can let out the helium into your lungs.
All of a sudden you have a different voice.
For instance, scientists the world over know
these symbols regardless of what language
they speak. Sodium, capital N and lower case
a, Na. Sodium doesn't start with Na for us.
So you obviously know that was probably a
scientist that was from a different country.
Now let's look at the properties and the atomic
numbers. You have your liquids. You have your
solids. You have your gases. Another known
interesting thing is you also have substances
that were made in a lab. At least, everything
from a to z, is going to be a combination
of all living things and non-living things
comes from this. If you wanted to put a combination
together, you could easily do that. Again,
the simplest one I can tell you is H2O. Two
parts hydrogen and one part oxygen and billions
and billions of atoms later makes you a glass
of water. That's how simple it is.
