Today, I will share with you a tale about how atoms came to be. A very long time ago, like over 2,000 years ago, that’s a pretty long time. Ryan Gosling wasn’t around yet; those were dark days. Anyways, 2,000 years ago a Greek dude called Democritus (great name)




Declared everything was made up of atoms.  Yes everything. That means you, me, trailers, Twinkies, pickles, kittens, spiders, tables, Ryan Gosling, everything, are made up of atoms.  In fact atoms come from, a Greek word. This word was atomos which means indivisible. Because, a ton of English words come from Greek ones. Like a ton.




Not that one though; that’s Japanese


Much later, in the 19th century, another guy named John Dalton refined the idea with his theory that atoms are the smallest particle of an element that retains its chemical properties. That means if you break apart an atom of a certain element, it is no longer that element. One small thing can make a very big difference.  Just like how the color of your nail polish can change your whole look! Now, on the periodic table of elements, they are arranged by their atomic number, which is their number of protons or electrons. When atoms bond together they make molecules. For example, water is a molecule. Its comprised of two hydrogen atoms and one oxygen atom, which is why it’s called H2O!
Atoms are made up of even smaller things, subatomic particles, called protons, neutrons and electrons. The center of an atom is a nucleus, much like the center of a cell, only it is a cluster of positive charged protons and neutral neutrons. They are held together by a thing called the strong force, and this keeps protons from repelling each other.  The nucleus is encompassed by a cloud of electrons moving about the speed of light! They orbit the nucleus in shells, depending on the different energy level, and each shell holds a different number of electrons. The further away from the nucleus, the more electrons there are.
Atoms are incredibly small, so most of the universe is actually filled with empty space. That’s probably why it’s called space. Because there’s so much of it! SPAAAAAAAACEEEEEEEE
