CSET Science: Chemistry

Subjects : cset, science, chemistry
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Components made up of a combination of atoms






2. Chemicals like sodium that react with water to make alkaline solutions. Part of Group IA. They easily lose their valence electrons to become +1






3. Radioactive decay in which half of a sample decays






4. Negative charged ions






5. Gases like neon and helium that do not interact with other elements because they havea complete valence shell






6. Hydrocarbons that include carbon - carbon triple bonds






7. When two different substances combine to form a new substance or when a substance breaks down to form two different substance.






8. Metals that have low melting points






9. Part of group VIIA and are highly reactive nonmetals. They have seven valence electrons and range from bein ggaseous to solids. Includes fluoride - chloride - and iodine






10. The outer electron in a shell






11. Energy released when an electron is added to a gaseous atom






12. Small component of an atom that has no electrical charge






13. The conversion of a gas back into a liquid






14. Occurs when one compound is replaced by an atom of another element like zinc metal






15. Hydrocarbons taht also include oxygen - like alcohols - carbohydrates






16. Move around the nucleus at the speed of light and have a negative charge






17. Carbons that consist of both hydrogen and carbon atoms and can be alkanes - alkenes - akynes - adn aromatics






18. Metals like calcium that produce alkaline solutions when combined with water. Part of Group IIA. Have two electrons in their outer shells






19. The center of an atom - which contains protons and neutrons






20. Distilled water - which has the ph level of 7






21. Radioactive decay that leads to the emission of gamma particles






22. Hydrocarbons that have single bonds with a prefix to show the number of carbon atoms - like methane - ethane - propane - butane - pentane - and hexane






23. When two reactants form one product - like sulfur dioxide by burning sulfur in the air






24. The chemical potential for hydrogen - which determines whether or not a chemical is an acid or base






25. Anything that has mass and takes up space






26. Measures of an attraction that an atom has ffor electrons in a chemical bond






27. Sodium






28. Ammonia






29. Metals mostly found in the middle of the table that are small and shiny. They are hard and have high melting and boiling points






30. When a compound breaks down into two or more substances by heating - like the break down of mercury oxide






31. The energy required to completely remove an electron from an atom or an ion to make it ositive. the energy increases from left to right as the atomic radius diecreases






32. Radioactive decay that leads to an emission of Helium -4 ion






33. 1.66 x 10^-24 g






34. The degree that two liquids can mix together






35. Radioactive decay in which a beta particle - aka an electron - is emitted






36. Metals that have a variety of property that include carbon - nitrogen and oxygen vital to the earth






37. Metals that conduct electricity






38. Small component of an atom that has a positive electrical charge






39. The idea that 1. gaes are made up of particles - 2. gas atoms do not exhibit intermolecular attraactions or repulsions - 3. gas particles are in continuous random motions - 4. collisiosn between two gas particles is not dissipated - and 5. the averag






40. The conversion of liquid into a gas






41. The way a periodic table is ordered in columns based on how many electrons are in the outer shell






42. The smallest form of a particle






43. The transition from a gas into a solid






44. An atom that has an electrical charge






45. Water






46. The way of ordering the periodic table based on how many protons there are






47. The process of balancing chemical equations






48. The different forms of an electron based on their neutrons






49. A chemical bond in which two atoms share electrons like H2.






50. The number of protons/electrons within an atom
