This does not look the same throughout/does not have evenly distributed parts.
Basic building blocks of all matter. These have the properties of a chemical element.
The matter may change its size, shape, texture, etc., but its chemical properties do not change. It may look different, but it is still the same substance you started with.
A combination of two or more substances that are physically (not chemically) combined. Each item retains its properties and can be separated out.
are formed when two or more DIFFERENT atoms combine/bond.
The amount of matter (stuff) in an object. Stays constant (same).
Is a subatomic particle located in the nucleus of an atom and has a neutral (or no) charge.
The temperature at which a substance changes from a liquid to a gas.
The center part of an atom where two of the subatomic particles are found.
These are made up of atoms that repeat due to the need to continue filling up the outer orbital. When they bond they make strong, solid, crystalline structures.
This looks the same throughout.
The amount of mass per unit of volume (ratio of mass and volume/how compact an object is).
Is a pure substance made from one type of atom. It cannot be chemically broken down anymore while still retaining its properties.
Is a subatomic particle located in the nucleus of an atom and has a positive charge.
These contain a few atoms held together by covalent bonds. The outer orbitals are filled due to the bonds, so nothing else can bond to it. It is also in its simplest form and is NOT a crystalline structure.
The temperature at which a substance changes from a solid to liquid.
A material that is only made up of one type of atom or molecule (i.e., element or compound).
The downward force exerted on an object due to gravity. Changes based on location.
The number of electrons in the outermost shell/orbital.
Chemical Change (Reaction)
When two or more substances interact and create a new substance. Signs of this occurring could be release of gas (bubbles), change of color, production of odor, release of heat and light, and production of loud sounds.
Anything that has mass and takes up space (volume). Can be a solid, liquid, or gas.
are formed when two or more of the same or different atoms combine/bond.
A characteristic that describes a substance as is without changing the identity of the substance (i.e., color, density, shape, size, etc.).
Is a subatomic particle located in the area outside the nucleus in the shells/orbitals/energy levels.
