The Nature of Life

3. Electrons are shared equally
4. outside of the cell membrane in plants, fungi, algae, and bacteria
5. Two or more elements united in a definite ratio by chemical bonds
7. The capacity to perform work or to produce a change
10. Energy is constant. It cannot be gained or lost, only converted from one form to another.
11. Formed when molecules lose or gain electrons
12. Electrons in outermost orbital can be removed from one atom and transferred to another atom
13. Fatty or oily substances that are mostly insoluble in water (fats and oils)
14. Electrons are shared unequally (like water)
17. When energy is converted to another form, it flows from a high energy state to a low energy state and releases energy during the conversion.
18. Combining capacity of an atom or an ion based on electron number
19. Two or more atoms bound together
20. Smallest stable subdivision of an element
21. Center of an atom
22. Structural units of organisms

1. Interior cell matrix
2. Study of energy and its conversions from one form to another
6. Positively charged particles
8. Neutral particles
9. numbers Number of protons
12. Form of an element that varies in its number of neutrons and atomic weight
15. Combined number of protons and neutrons
16. Negative electric charges circling the nucleus
