This is the smallest unit of an element.
atom
molecule
compound
nucleus
Any combination of two or more atoms that are chemically combined is called this.
molecule
compound
element
pure substance
This is any combination of two or more atoms from different elements that are chemically combined.
compound
molecule
element
pure substance
The basic building blocks of the universe. The smallest and most pure substances that can be found.
elements
atoms
molecules
compounds
These are what determine the properties of every atom and make one element different from another. They have a positive charge (yes, I'm positive that it's a positive charge).
protons
electrons
neutrons
nucleus
These hang out in the nucleus and don't really affect the properties of the atom that much. They don't have any charge (so they can't use credit cards).
neutrons
protons
electrons
atomic numbers
These are what form chemical bonds as atoms share or take them from one another. They orbit the nucleus and have a negative charge (but they are still happy about things in general).
electrons
electron clouds
protons
neutrons
This is the central region of an atom and where protons and neutrons hang out (but the protons and neutrons still follow proper social distancing rules!).
nucleus
electron cloud

atomic number
This is a list of the 118 known elements that exist (and a picture of it is on this quiz!).

This is anything that has mass and takes up space (meaning it has a volume).
matter
mass
element
