Across
- 3. smallest significant particle of atom, negative charge, orbit the nucleus
- 5. a principal particle of an atom, no electric charge, found in nucleus of atom
- 6. central core of an atom, made up of protons and neutrons
- 10. family of particles (as electrons, muons, neutrinos) that experience no strong forces
- 13. an atom that has gained an electron, has more electrons than protons, has negative charge
- 14. matter that exists in extreme heat, like in stars
- 16. substance that has mass & takes up space
- 17. form of matter doesn't have definite shape has volume
Down
- 1. a variation of an atom based on the loss or gain of an electron, this changes charge of an atom
- 2. a principal particle of an atom, has positive charge, found in nucleus of atom
- 3. specific form of matter composed of only 1 type of atom
- 4. an atom that has lost an electron, has more protons than electrons, has positive charge
- 7. the science of materials that make up universe
- 8. form of matter that has definite shape & volume
- 9. 2 or more elements combined chemically, separated by chemical means
- 11. matter that has no definite shape, weight, or size
- 12. smallest form of matter, made of smaller particles-protons/neutrons/electrons
- 15. 2 or more elements combined physically not chemically, can be separated by physical means
