Basic Chemistry

2. weak electric forces that attract neutral molecules to one another in gases
5. Type of molecule, often polar, that interacts with water by dissolving in water and forming hydrogen bonds with water molecules.
7. The ability of water molecules to cling to each other due to the process of hydrogenbonding
11. Substances that is dissolved in a solvent forming a solution
15. Chemical bond in which ions are attracted to one another by opposite charges
17. Chemical bond in which atoms share one pair of electrons
18. substance or a group of substances that tend to resist pH changes of a solution
20. A group of atoms bonded together
22. A diatomic molecule that comes from water with a hydrogen removed
25. Force that holds moist membranes together due to the attraction off water molecules through hydrogen bonds
28. Number of protons within the nucleus of an atom
29. Mass of an atom equal to the number of protons plus the number of neutrons
30. Positive subatomic particle located in the nucleus
31. Anything that takes up space and has mass
32. Substance having two or more different elements in a fixed ratio
33. Atoms of the same element having the same atomic number but a different mass number due to a variation in the number of neutrons
34. Measurement scale for hydrogen ion concentration
36. Substances that cannot be broken down into substances

1. Type of molecule that is typically nonpolar and therefore does not interact easily with water
3. The ability of water molecules to cling to, or be attracted to, a surface, such as a transport vessel in a plant or animal
4. The nucleus of a hydrogen atom separated from its accompanying electron
6. Charged particle that carries a negative or positive charge
8. Neutral subatomic particle, located in the nucleus
9. The branch of science that deals with the identification of the substances
10. molecules tending to lower they hydrogen ion concentration in a solution and thus raise the pH numerically
12. The observation that an atom is most stable when its outer shell is complete and contains eight electrons
13. Smallest particle of an element that displays the properties of the element
14. Average of atom mass units for all isotopes of an atom
16. Fluid that contains a dissolved solid
19. The ability of an atom to attract electrons toward itself in a chemical bond
21. Weak bond that arises between a slightly positive hydrogen atom of one molecule and a slightly negative atom of another molecule
23. The outer electron shell of an atom
24. A set of symbols showing the composition of a chemical compound
26. Negative subatomic particle, moving about in an energy level around the nucleus
27. Symbol of an atom
35. molecules tending to rise the hydrogen ion concentration in a solution and thus to lower its pH numerically
