Properties
I am properties. I can be either physical or chemical. I describe chemicals. When a physical change occurs, like changes in color, shape, or size, I can describe the object physically. When a chemical change occurs, like in baking, I can describe the product chemically. Physical properties of a chemical include color while chemical properties of a chemical include atomic structure.
Matter
I am matter. I am created of atoms. I can exist in either solid, liquid, gas, or plasma state. Sometimes I can change from one to another. This occurs either chemically or physically. I am also anything that has mass.
Atom
I am an atom. I make up the matter all around us. I am created of two main parts: a nucleus and electrons. My nucleus is made up of protons and neutrons. My electrons orbit madly around my nucleus. There are many different kinds of me, which can be found on the periodic table. I am extremely small, but make up every single thing.
Atomic Number
I am an atomic number. I am the number of protons contained in an atom. I am found on the periodic table. I can also describe how many electrons are in an atom. You can use me along with atomic mass to determine how many neutrons are contained in an atom.
Atomic Mass
I am atomic mass. I am the number of protons and neutrons in the nucleus plus the number of electrons in an atom. I am the average mass of one atom of an element. I can also be found on the periodic table. If you subtract an atom's atomic number from me, you will get the number of neutrons in an atom.
Proton
I am a proton. I am positively charged. I am also found in the nucleus. I am relatively heavy. If you compared me to an electron, I would be a marble and it would be a speck of dust several feet away. There are an equal number of electrons and myself in an atom.
Neutron
I am a neutron. I have no charge. However, I have the same mass of a proton. I am also found in the nucleus of an atom. You can determine how many of me there are by subtracting my atom's atomic mass from its atomic number, or how many protons/electrons are in it.
Electron
I am an electron. I have a negative charge. I am found whizzing around the nucleus of an atom. My path is relatively circular around the nucleus, but I am not the best at keeping a perfect path. I also define how much volume or space an atom takes up. Between the nucleus and myself is just a bunch of empty space. I am kept inside shells or energy levels.
Shells or orbitals
I am shells or orbitals. Sometimes I am even energy levels. I am the areas surrounding the nucleus of an atom and also the holding place of electrons. Some of me can hold lots of electrons and some can only hold a few.
Nucleus
I am the nucleus. I am composed of protons and neutrons. Surrounding me are electrons. They orbit spaztically aroung me in different energy levels, also known as shells or orbitals. Despite the fact that I am much smaller than the atom itself, I contain most of an atom's mass.
Elements
I am an element. I am any material mad of one type of atom. I cannot be broken down to a simpler substance. Only 90 of me make up this planet. On the periodic table, I am represented by an atomic symbol. I am also described by atomic numbers and masses of one atom of my type.
Compounds
I am a compound. I am made of more than one different kind of atom. I am formed when two or more elements chemically combine. Physical forces cannot break me down, however chemical forces can. When two elements combine to form me, they lose their individual traits.
Density
I am density. I am the amount of matter per unit volume of a specific substance. I am a physical property of matter. You could say that I am how closely packed an object's molecules are. For example, a rock would be much more dense than a piece of styrofoam the same size. I can be found by dividing mass by volume.
Gas
I am gas. The atoms that make me up are very spread out. My molecules are fully of energy and bounce around all the time. I make up the atmosphere. I am composed of random groups of atoms. I can fill any container of any shape or size. Anther name for me could be vapor. I am the air you breathe.
Liquid
I am liquid. The atoms that I am made of are more spread out than a solid, but less than a gas. I am the state of matter between solid and gas. I don't have to be made up of the same compounds. I can fill up the shape of a container. I have a definite mass, but not a definite volume.
Solid
I am solid. The atoms that I am composed of are very close together and compact. They can barely move. Because of this, I can hold my own shape without the help of any container. I can have pure elements or a variety of compounds.
