atoms and elements

2. how much space something takes up
3. amount of stuff something contains
4. a state of matter with no definite shape but has a definet volume
5. a substance made up of atoms of two or more different elements joined by chemical bonds
7. how much mass is packed into a specific volume
11. the internal energy of a substance from the random motion
12. a state of matter with a definite shape and volume
14. the amount of force exerted per unit area of a surface
16. when matter transforms from one physical form (solid, liquid, or gas) to another

1. a strong electrical attraction holding atoms or ions together to form stable compounds
3. a group of atoms that are held together by chemical forces; a molecule is the smallest unit of a compound that keeps all the properties of that compound
6. a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns.
8. a substance that cannot be separated or broken down into simpler substances by chemical means
9. a sample of matter, either a single element or a single compound, that has definite chemical and physical properties
10. the smallest unit of an element that maintains the properties of that element
13. everything is made out of
15. a state of matter with no definite shape or volume
