So we have a few different ideas from dalton's atomic theory.
00:06
So one of them is that everything's made up of tiny particles.
00:11
We call these atoms.
00:13
So we have atoms.
00:15
The second part is that not all elements are identical, some of them are different.
00:20
So we have different types of atoms.
00:25
Now, i know this seems kind of commonplace now, but this was actually pretty groundbreaking at the time.
00:30
So we have different types of atoms.
00:32
We call these elements.
00:35
They're kind of like different flavors of the atoms.
00:37
They all do different things and behave in different ways...
