Across
- 2. structure a structure whose subunits occur in a constant ratio and are arranged in a repeating pattern; the subunit can be individual atoms or a molecule
- 3. the specific way in which the bonds and atoms are arranged within the molecules of a substance
- 4. a characteristic of matter
- 6. the connection between atoms in more complex particles
- 8. matter that has a constant chemical composition and characteristics
- 10. an individual particle of an element
- 12. a unique particle of matter that is a fundamental building block of matter
- 14. shorthand notation of one, two, or three letters that represent the name of the element
- 17. a property that describes the mass of a certain volume of matter
- 18. a property that describes how well one substance dissolves in another substance
Down
- 1. the types of elements that make up a substance, as well as the specific ratios of atoms of each kind of element that make it up
- 5. a table that lists all of the known elements and groups them into columns by important shared properties
- 7. the amount of matter in an object or sample; mass is measured in grams
- 9. a type of extended structure that is made of many smaller, repeating subunits in a chain; the repeating subunit is a unique molecule
- 11. the mass of a single atom; all atoms of an element have approximately the same atomic mass.
- 13. a group of two or more atoms that are held together by chemical bonds; a molecule has a unique composition and structure
- 15. a representation of an object which makes important aspects easier to see
- 16. a solid structure whose atoms or molecules are arranged in a repeating, three-dimensional pattern
