you probably already know that everything is made up of little tiny things called Adams you might even know that each atom is made even more particles protons neutrons and electrons and you probably heard that atoms are small  I have never thought about how small atoms really are answer is that they are really really really small so you ask let's ask this question how many atoms are in a grapefruit is made up of only nitrogen atoms at all true but there are nitrogen atoms in a grapefruit go to help you visualize this let's blow up each of the atoms to the size of a blueberry how big would the grapefruit have to be  how do the same size of actually the Earth that's crazy I feel the Earth with blueberries I would have the same number of nitrogen atoms as a grapefruit that's right how big is  I do know what you catch even more crazy let's not look inside of each that's the blueberry right what do you see there in the center of the atom of something called the nucleus which contains protons and neutrons and on the outside electrons big is the nucleus of atoms are like blueberries in the Earth how big would the nucleus be you might remember the old pictures of the atom from your science class where you saw this The Herald points nucleus will those pictures while they're not drawn to scale so they're kind of wrong so how big is the nucleus searching for the nucleus  you know what it would be in the visible it's too small to see  okay let's blow Pia blueberry to the size of a house fairly be visible to get our lines wrapped around how big the nucleus is we need to blow up the blueberry up to the size of a football stadium Apple the size of a football stadium in a right smack-dab in the nucleus the size of a marble  and there's more if I haven't blown your mind by now let's consider the atoms immoral it contains protons neutrons and electrons the protons and neutrons inside of a nucleus in kitchen almost all of the mass of the atom on the edge of a football stadium Trans on the edge what is it between the nucleus and the electrons that's really empty between the nucleus and the electrons there are vast regions of empty space now technically there are some electromagnetic field December this vast region of empty space is inside the blueberry which is inside the earth which really are the atoms in the grapefruit okay one more thing if I can even get more bizarre since virtually all the mass of an atom is in the nucleus and now there is some amount of mass in the electron spend most of it is in the nucleus how dense is the nucleus the density of a typical nucleus is 4 * 10 - 17th term for meter cute but that's hard to fit in English units 2.5 x 10 to the 16th pounds per cubic feet okay that's still kind of hard to figure okay here's what I want you to do make a box that is 1 foot by 1 foot my cars on average weight to tons how many cars does nuclei would you have to put into the box to have your one foot box have the same density of a nucleus nope nope nope that is almost equal to the number of people in the earth so if everyone of the Earth on their own car and they don't  we put who's cars into your box  that would be about the density of a nucleus  so I'm saying that he can chew every car in the world and put it in your window you would have the density of one nucleus let's review the atom is really really small the grape fruit like blueberries in the Earth the nucleus is crazy small inside the blueberry and blow it up to the size of a football stadium now the nucleus is a marble in the middle  the atom is made up of fast regions of empty space crazy high-density I think I'm putting all those cars in your one foot box I think I'm tired
