atomic terms
Term | Definition |
---|---|
Matter | everything that has mass and takes up space |
Element | matter that consists of only one type of atom |
Metals | Good conductors malleable may be solid or liquid |
nonmetals | bad conductors may be any state |
semi-metals | sometimes like metals sometimes like none metals |
atom | The basic building block of matter |
atomic theory | that everything is made of atoms |
compound | matter that is made up of two or more types of atoms |
molecule | the smallest part of a compound that still acts like that compound |
proton | positively charged and found in nucleolus |
Solid | a substance that has a definite shape and volume because the atoms are only able to vibrate in place. |
Liquid | has no definite shape but a definite volume and will form to the shape of its container. This is because the atoms can glide past each other but have forces holding them together. |
Gas | Without ether a definite shape or volume gas will spread out evenly to fill its container. |
PLasma | Happens at extremely high temperatures made of the particles that make up atoms and has no definite volume of shape but can conduct electricity. |
Freezing | When a liquid turns into a solid at cold temperatures because the atoms slow down. |
Melting | When a solid turns into a liquid because of high temperatures and the atoms speeding up. |
Evaporation | When a liquid turns into gas because of high temperatures. This has two forms. |
Condensation | When a warm gas hits a cool solid it turns to liquid because this happens. |
mixture | is a combination of two or more substances that can be separated easily. |
solution | is a combination of two substances that can not be separated easily. |
