Across
- 3. compounds that will interact with water; "water loving"
- 4. anything that takes up space
- 6. rain whose pH level has been skewed toward the acidic side of the pH scale , with air pollution being the cause of this shift
- 7. compounds that do not interact with water; "water fearing"
- 10. one of three primary constituents of an atom, possessing no electrical charge and found in an atom's nucleus; isotopes are defined by the number of these in an atom
- 11. type of covalent bond in which electrons are shared equally between atoms
- 13. membrane-lined compartment that encloses the primary complement of DNA in eukaryotic cells
- 15. chemical bond that links an already covalently bonded hydrogen atom with a second, relatively electronegative atom
- 17. physiological systems that function to keep pH within normal limits
- 20. measure of the strength of attraction an atom has for electrons that are being shared in a covalent bond
- 24. measure of the quantity of matter in any given object
- 25. difference in electrical charge at ne end as opposed to the other
- 26. chemical bond in which atoms share pairs of electrons
- 29. mixture of two or more kinds of molecules, atoms, or ions that is uniform throughout
- 30. basic constituent of an atom, found in the nucleus of an atom; has a positive electrical charge; elements are defined by the number of these in their nucleus
- 31. number of protons in the nucleus of an atom; all elements are ordered on the periodic table by this
- 34. the amount of energy required to raise the temperature of a substance by one degree Celsius
Down
- 1. scale used in measuring the relative acidity of a substance
- 2. the process of chemical combination and rearrangement
- 5. what is doing the dissolving
- 8. strongly basic OH- ion, often used to shift solutions toward neutral or basic on the pH scale
- 9. type of covalent bond in which electrons are shared unequally between atoms, so that one end of the molecule has a slight negative charge, and the other end a slight positive charge
- 12. states that matter is neither created nor destroyed in a chemical reaction
- 14. what is being dissolved
- 16. compounds made up solely of hydrogen and carbon atoms
- 18. one of three basic constituents of an atom; carry a negative electrical charge and are distributed in an atom a distance from the nucleus
- 19. chemical bonding in which two or more ions are linked by virtue of their opposite charge
- 21. collection of the atoms of two or more elements that have become linked through ionic bonding
- 22. a charged atom; an atom whose number of electrons differs from the number of protons
- 23. form of an element as defined by the number of neutrons contained in its nucleus
- 27. solution that is also known as basic
- 28. a substance that is "pure"; cannot be reduced to a simpler set of component substances through chemical processes
- 32. entity of consisting of a defined number of atoms covalently bonded together
- 33. any substance that accepts hydrogen ions in aqueous solution
- 35. any substance that yields hydrogen ions when put in aqueous solutions
