Supernova is the most powerful explosion entire universe the spectacular even billions I plan to live until what are the great scientific where are the elements the basic building blocks of all matter I don't know what's an element what's not properties of the different elements have is it possible to group The Elements and chemical property actress enemy almond House of Furniture the universe simple science material what's it made of send a problem we can separate a mixture mechanically by picking up the pieces so we called her a mechanical mixture what are in the ocean isn't this substance either it's a mixture of water. separate the solution operating the water behind it can tell the difference between distilled water and salt water solution by using a conductivity meter custody are Waters and ancillary it hardly at all pure substance can be a compound or an element either way with nothing else compounds contain two or more kinds of atoms chemically bound together elements contain only one type of atom are chemically identical to each other for all of us the water speaker has been distilled and deionized everything but watermelon can the Kauffman Tire Repair water conduct electricity right you have to create a conducting Solution by dissolving and I are at the situation exactly when is the bank open after Addis for electrolysis the road about Roosevelt stop the reservoir are from the collecting tube by opening the valve slowly been holding them it's working yea gas bubbles electrode pure compound when water molecules are decomposed by electricity or drinking heat energy and they break new Bond immediately hydrogen atoms form a two guys an oxygen atom form 02 cast where did element originally come from The Big Bang is where it all started about 15 billion years ago the universe with condensed into a very microscopic Point all matter of all energy started in an instant pot explosion of all around the same time at the very beginning there was only the most subatomic particle was far too hot for anything like we know the man that we know around to go exempt but after about 100 seconds after the big bang it cool down enough so that the elements that we know of hydrogen and helium started perform years after do you know what this boats made entirely a 77% hydrogen 23% helium and just up a lithium the physical properties of elements organize the elements into categories that describe their physical properties for example metal or nonmetal elements that are shiny conductive and Bendel metal elements that don't have these physical properties are classified as an ornament take a pic the copper to the metal or a nonmetal pause the copper with a steel wool conductivity meter tell me electricity flowing copper the conductor I've changed its shape dependable obviously copper the metal not the type of properties of metals and nonmetals are three elements for band bility suppose that was steel wool definitely Shawnee show me pictures of spring-trap unacceptable I can f*** you with my finger how to be a metal phone number to install a golfer anime doctor how do I get to stay that it's very brittle example of carbon Ashanti when I post it what tomatoes are the conduct electricity when I bend it brakes so what are we can you draw properties of carbon and silicon to classify couldn't connect electricity it doesn't Bend subnautica shiny superconductor they each have two properties of metal and non-metal unique class of elements called metalloid a metal or nonmetal Universe At the very beginning was very simple place it was huge clouds of hydrogen and helium and a pinch of lithium of those files would start to condense the cloud into the Stars very sick picture of the Stars the temperatures in the pressures are enormous the temperature of the core of a star can be 10 million degrees at these temperatures and pressures hydrogen atoms together in a process called Thurman produce atoms of helium and as the temperature goes on in the pressure go up the more complex atoms like carbon and neon all the way up inside Beast arms I'm turning the physical properties of the element plus 2 divided into metal and gas has fallen to the metal and metalloid falling between front properties of both metals and others don't seem to react at all but we can tell a lot together the lab to experiment with metal sodium magnesium costume Intel well we'll see what metal reacts with water according to the results of the results already a piece of sodium metal Chinese stir fry put the rest back in st. George put up a slice into the water close look at it go turn the volume up to the surface or light jacket magnesium metal in water here goes Anna bikini bubbles thirsty Quaker bottle with no bubbles available idea that's what happens when we increase available energy okay what's going on Rockford public burning looks like what's the weather metal doesn't water Wicked at the Samaritan okay so based on what we've observed other similarities in the reaction that's Papa's group has elements with water looks like it was on fire what's Tony had a breakdown react to bring it up to the surface 30 minutes group what about calcium and magnesium turn off the surface and the twins are not nearly they're probably going to separate group good work you got all these elements trapped inside the stars but a small amount of stars with the massive star during ends 100 times the mass of the Sun and the lies violently as the core of the star runs out of that nuclear deal that's keeping the star going to start then turn on itself and the rebound. cause of a supernova explosion explosion of a star and those elements can go into Interstellar space from other stars planets and even you and I the non-metallic elements Ranch Ohio reactive or unreactive reaction the cruising need to group them together what's up reactivity with or nonmetal Argon Neon chlorine I'm tired I'm all right so smart metals react with Metals sample Panthers are reactions to Woburn flooring gallery toxic Berry's country music. Reacts with the steel wool nausea reaction you're right don't converted to any reaction bargain Dance Supply no color doll is it reactants I can't see anything set alarm to reactivate your right list of Nyan Cat Sports truth put in the to the wall it looks like me on geography observation so we're testing iodine what's a hyper reactive Pittsburgh what's up what do you mean you think we can move any of these elements together what is the time in the wrong group what about chlorine and iodine weather thermostat hydrogen and oxygen brought together in the right combination produces water Watercourse least Huron meter is one of the most important compounds for the formation and maintenance light carp has got to be single most important element for life on Earth carbon has the how to make the most enormous number of complex molecules from simpler molecules like sugar all the way up calcium in our bones iron in our blood call came from inside the Stars billions of years ago early days of science researchers have been looking for patterns what time the element by the 1860s amount of all that was available in 1872 only when I'm delay of organization of the elements and Milestone to predict the properties of elements but haven't even been discovered yet the Mendeleev table the elements were listed in order in the new role and similar chemical behavior we repeated periodically that's why it's called the periodic table turn the lamp all cable channels calcium and magnesium are in a group don't know each other and we have neon and argon I got the bottom Aaron are really why not remember people that was made in 1872 so what exactly do astronomers look for or signs to look for when they're staring the possibility of life on other planets first of all temperature a peach too hot and can't be too cold just write the temperature necessary for liquid water at least like your other appears to be after that it would be nice what is the most liked likes to have an atmosphere and course there has to be a certain amount of chemical chemical in the oceans are in the water the Stars at the planet Earth around has to be stable you can't live Fort Lee short. Of time for flight unstable Journey like our son that's order some of the things you look for when you're considering the possibility of life on other planets Savannah Honda the mysterious story of the elements with their physical properties are chemical behavior center periodic pattern I think that most of them even someone's needs to vitamins he'll keep her out of the carbonation star going Supernova the universe may seem chaotic the border at play and finding
