Across
- 2. matter with a definite weight, volume and shape
- 4. link protein bonds together (hint: salt bonds, hydrogen bonds, disulfide bonds, van der waal bonds)
- 8. all matter that is not alive and have never been living, does not contain carbon
- 11. the smallest complete unit of an element
- 12. the five elements that make up the amino acids found in hair
- 13. have a negative charge, make it possible for atoms to bond (hint: major part of electricity)
- 14. change in physical characteristics of a substance without creating a new substance
- 17. definite weight but no definite volume or shape
- 19. have no charge, determines the weight of an atom
- 21. result of unlike charges attraction, makes up 35% of the hairs resistance, not very strong, broken by heat, water or a change in pH
- 22. end bonds connecting amino acids together
- 23. matter with a definite weight and volume but no definite shape
Down
- 1. two or more atoms joined together by a chemical bond
- 3. when sulfur type side chains join with other sulfur type chains, stronger than other bonds, broken by chemical processes
- 5. compounds consisting of oxygen. hydrogen, nitrogen, carbon and sulfur
- 6. a change in substance the creates a new substance with chemical characteristics different from the original substance
- 7. very weak bonds,easily broken by heat and water, makes up 35% of the hairs strength
- 9. all matter that is living or was living at one time, carbon is present
- 10. have a positive charge, used to identify an atom
- 15. basic substances that cannot be broken down into simpler substances
- 16. anything that occupies space
- 18. the scientific study of matter and the physical and chemical changes of matter
- 20. a form of protein that makes up 97% of hair
