everything in the entire universe is made of atoms. 70% of the universe is hydrogen Atoms, which have been compressed to make stars, and stars that explode at the end of there life, either go into a supernova and become a Black Hole, or they explode and become red giants, which will then die and become white dwarfs, which will die eventually (After billions of years) and will then become black dwarfs, when the universe goes dark leaving only black dwarfs, and black holes. but since that is so far in the future, when that happens, it pretty much will be forever. White dwarfs might also be our last hope in the universe, because they are so hot, and they are so small. Because they are the corpse of a star, they will have about half the mass of the previous star, which is all compressed to about the size of the earth. Because they have that mass at that size, the density on them is very high, making it so if you step in a white dwarf, it will flatten you into a pancake.Important things:Molecules build but don’t make new moleculesPhysical changes are reversible but not chemicalAll things are made of molecules, so air could react with the metal.Molecules are not straight but combine in all ways.Molecules react with each other making other substancesReactants can change smell,color,weight etc. when combinedFire Puns are badVocabAtom: the smallest particle of a substance that can exist by itselfMatter: a physical substance that possesses and occupies massNew substances form by atoms  connecting together and form a  molecule.

substances are made of atoms or groups of atoms that repeat.

# data[].attributes.body
Elements: Crucial part(s) of a system.

# data[].attributes.body
Important things:

Molecules build but don’t make new molecules

Physical changes are reversible but not chemical

All things are made of molecules, so air could react with the metal.

Molecules are not straight but combine in all ways.

Molecules react with each other making other substances

Reactants can change smell,color,weight etc. when combined

Fire Puns are bad

Vocab

Atom: the smallest particle of a substance that can exist by itself

Matter: a physical substance that possesses and occupies mass

reactions are not always explosive. Except when you add sodium (not salt, the metal) to water that reacts and causes pressure waves in the water resulting in an explosion.

If you have noticed one of the periodic tables

# data[].attributes.body
If you have noticed one of the periodic tables, elements have different names than what we call them at home. they also have categories such as gas solid or earth metal

# data[].attributes.body
Reactants can change smell, color, weight etc. when combined

# data[].attributes.body
combining certain elements will add density or weight to the substance.

Our oxygen can produce and make new molecules

rust is a chemical reaction of molecules and iron atoms. Atoms and atoms don't combine and make a new atom, they make a molecule.

New substances form by atoms  connecting together and form a  molecule. For example iron molecules and oxygen molecules combined and form rust. This is the something with other substances like water, it has hydrogen and oxygen molecules .

a part or aspect of something abstract, especially one that is essential or characteristic

# data[].attributes.body
elements can combine to make different things, like two hydrogen Atoms and one oxygen Atom

# data[].attributes.body
there are multiple parts or elements in a single molecule. for instance, a water molecule is the product of 2 hydrogen and 1 oxygen atom.

Atom: the smallest particle of a substance that can exist by itself

Matter: a physical substance that possesses and occupies mass

# data[].attributes.body
New substances formed because there is such thing as a chemical reaction. It is when two elements combine to form a new substance. Element are the main well, ingredients of life and everything.
