Elements and Atoms

  • 0:03 - 0:06
    We Humans have known for thousands of years, just looking at our environment around us that
  • 0:07 - 0:10
    there are different substances, and these different substances tend to have different properties, and
  • 0:12 - 0:15
    not only do they have different properties; one might reflect light in a certain way, or not reflect light
  • 0:18 - 0:20
    or be a certain colour, or at certain temperature be liquid, or gas, or be a solid,
  • 0:22 - 0:25
    but we also start to observe how they react with each other in certain circumstances.
  • 0:28 - 0:31
    And here's pictures of some of these substances. This right here is Carbon, and this is in it's graphite form;
  • 0:31 - 0:36
    this right here is Lead, this right here is Gold,
  • 0:39 - 0:41
    and all of the ones that I've drawn, that I've shown pictures of here, and I got them all from this website right over there
  • 0:41 - 0:45
    all of these are in their solid form, but we also know that
  • 0:47 - 0:49
    it looks like there's certain types of air, you know, certain types of air particles,
  • 0:49 - 0:52
    and depending on what type of air particles you're looking at
  • 0:55 - 0:58
    whether it is carbon, or oxygen, or nitrogen, that seems to have different types of properties,
  • 0:58 - 0:59
    or there are other things that can be liquid,
  • 0:59 - 1:02
    or even if you raise the temperature high enough on these things,
  • 1:02 - 1:05
    if you raise the temperature high enough on Gold or Lead
  • 1:05 - 1:07
    you could get a liquid,
  • 1:07 - 1:10
    Or if you kind of - if you burn this Carbon
  • 1:10 - 1:12
    you can get it to a gaseous state,
  • 1:12 - 1:13
    you can release it into the atmosphere,
