| matter | is anything that has mass and takes up space
🗑
|
||||
| substance | is a single kind of matter that is pure, meaning it always has a specific makeup or composition and a specific set of properties.
🗑
|
||||
| physical property | is a characteristic of a pure substance that be observed without changing it into another substance
🗑
|
||||
| chemical property | is a characteristic of a pure substance that describes its ability to change into different substances
🗑
|
||||
| element | is a pure substance that cannot be broken down into any other substances by chemical or physical means
🗑
|
||||
| atom | is the basic particle from which all elements are made
🗑
|
||||
| chemical bond | when atoms combine the force of attraction between two atoms
🗑
|
||||
| molecule | when atoms combine to form larger particles of two more atoms held together by chemical bonds.
🗑
|
||||
| compound | is a pure substance made of two or more elements chemically combined in a set ration
🗑
|
||||
| chemical formula | representation of a compound showing the elements and their ratio
🗑
|
||||
| mixture | is made of two or more substance that are together in the same place but NOT chemically combined.
🗑
|
||||
| heterogeneous mixture | you can see the different parts or substances
🗑

🗑
|
||||
| exothermic change | change in which energy is given off or released
🗑
|
||||
| chemical energy | the energy stored in the chemical bonds between atoms is a form of energy.
🗑
|
||||
| electromagnetic energy | a form of energy that travels through space as waves
🗑
|
||||
| electrical energy | is the energy of electrically charged particles moving from one place to another
🗑
|
||||
| electrode | used in electrolysis are the two metal strips are placed in a solution not touching one another for an electric current to flow through solution.
🗑
|
||||
