Ability to react
When a substance has the potential to react with acid, oxygen or water; a chemical property.
The smallest unit of matter. ex. a carbon atom
a change in matter that results in the formation of new substance with new properties
a property of matter that describes a substance based on its ability to change into a new substance with different properties; reactivity and flammability
a process in which chemical bonds are broken and atoms rearranged. During the process a new substance is formed.
2 or more elements combined to make a new substance,
Ex. Na (sodium) + Cl (chlorine) = NaCl (salt)
To change from a gas to a liquid; a physical change.
The measurement of how much mass of a substance is contained in a given volume; compactness of matter.
A substance that cannot be broken down into smaller parts. Composed of identical atoms.
To change from a liquid to a gas; a physical change.
Ability of a substance to ignite, causing fire or combustion; a chemical property.
A state of matter with no definite shape or volume; a physical property.
A state of matter that has a definite volume but no definite shape; a physical property.
The amount of matter in a substance; a physical property.
Anything that has mass and occupies space; a physical property.
To change from a solid to a liquid. Phase Change; a physical change.
A chemical reaction in which a substance, such as iron, combines with oxygen to form a new substance.
A change in the state of matter. ex. going from a solid to a liquid; a physical property.
A change in matter that does not result in a new substance or change of identity.
A property of matter that can be observed or measured, without the identity being changed.
A state of matter distinct from solid or liquid or gas and present in stars and fusion reactors.
The substance(s) that are formed/released in a chemical reaction.
A state of matter that has a definite volume and a definite shape; a physical property.
State of Matter or Phase of matter
The state in which matter can exist: solid, liquid and gas; a physical property.
The measure of the amount of thermal energy in a substance; a physical property.
The appearance and feel of a surface; a physical property.
The amount of space an object takes up; a physical property.
able to be hammered flat; easily shaped
can be pulled out into a wire.
Easily broken; not flexible
able to reflect light
The ability of an object to transfer heat or electricity to another object.
ability of an element to attract magnetic materials
Elements characterized by physical properties that include shininess, malleability, ductility, and conductivity.
Elements that are generally gases or dull, brittle solids that are poor conductors of heat and electricity
An element that has characteristics of metals or nonmetals and is a semiconductor
an arrangement of elements in which the elements are separated into groups based on their chemical and physical properties
Elements found on the left side of the Periodic Table
Elements found on the right side of the Periodic Table
Elements found along the stair step of the Periodic Table
How to find the number of elements in a compound
count the capital letters
How to find the number of atoms in a compound
if there is no subscript then there is 1 atom; if there is a subscript then that is the number of atoms
