Matter

4. The process in which something transforms from the solid phase to gaseous phase without turning to a liquid first.
5. A physical change when matter goes from a gas to a liquid. For Example: water that forms on the outside of a cold cup
10. Atomic _______ The number of protons in the nucleus of atom (the number of protons is also the number of electrons-they balance each other out)
12. table a way of organizing elements according to their atomic number and properties.
14. two or more elements that are chemically bonded. Identified by a formula. Ex. H2O = Water
17. Positively charged particle of an atom
18. The very small center core of an atom made up of protons and neutrons
19. The property of a substance to dissolve Examples: salt in water, sugar in sweet tea. Sand and water are non-soluble. The sand will sink.
20. A liquid becoming a gas
21. A pure, simple substance that can't be broken down into any other substance
22. or more atoms bonded together

1. _____________ property is a characteristic that can be observed or measured without changing the substance.
2. Atomic _______ The sum of the protons and neutrons in the nucleus. Measured in AMU's(atomic mass units)
3. they retain their individual properties. Ex. salt and water (make ocean water)
6. Neutrally charged particle of an atom (no charge)
7. The “curve” in the graduated cylinder
8. Negatively charged particle of an atom
9. The smallest particle of an element; the building blocks of all matter
11. Anything that has mass and takes up space
13. _____________ property is a characteristic that is related to changing the substance into something else
15. The amount of matter in an object (grams)
16. The ability to react with oxygen
20. The amount of space an object takes up
