Across
- 3. the major component in a solution
- 6. when two nonmetals combine, they form this type of bond
- 13. can cause a reduction in fish populations
- 14. this can be increased when stirring, heating, or increasing the surface area of a solid or liquid
- 15. a family of nonmetals, contain 7 valence electrons, and are highly reactive
- 17. bonds between metals and non metals, where valence electrons are donated
- 20. water is considered to be this, because it contains polar covalent bonds
- 21. determine the reactivity and chemical properties of elements
- 22. when an element has the same number of protons and electrons, but different numbers of neutrons
- 23. the molecules in this state of matter are packed tightly together and have low kinetic energy
Down
- 1. when this layer is depleted, it can cause skin cancer
- 2. donate two valence electrons
- 4. an example of an endothermic reaction
- 5. states that matter is neither created nor destroyed, but rearranged
- 7. a reaction where the potential energy increases because the energy is absorbed
- 8. causes high surface tension in water
- 9. the ability to float
- 10. a type of reaction that occurs on the Sun; two nuclei are combined together, producing Helium
- 11. a type of reaction that produces harmful radioactive waste when the nucleus of Uranium is split apart
- 12. the state of being thick, sticky, and semifluid in consistency
- 16. this family group contains a full octet, or valence shell; completely stable
- 18. a reaction where the potential energy decreases
- 19. the minor component in a mixture
