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. The conversion of a gas back into a liquid






3. Negative charged ions






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






5. Hydrochloric acid






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






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






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






9. The process in which a solid can become a gas - like dry ice






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






11. Organic compounds that contain nitrogen - including protein






12. 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






13. Anything that has mass and takes up space






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






15. The smallest form of a particle






16. Metals that have low melting points






17. The degree that two liquids can mix together






18. Ammonia






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






20. 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






21. Water






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






23. The transition from a gas into a solid






24. Hydrocarbons that involve carbon - carbon double bonds






25. The size of an atom that decreases across a period. Within the group - it increases from top to bottom






26. 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






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






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






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






30. The process of balancing chemical equations






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






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






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






34. The conversion of liquid into a gas






35. Radioactive decay in which half of a sample decays






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






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






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






39. A chemical that is sour and stings and receives positive charged atoms when they are dissolved in water






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






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






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






43. Substances that create hydroxide ions - have a pH level higher than 7 - and can conduct electricity






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






45. An atom that has an electrical charge






46. The bond formed when an anion and a cation unite and form a chemical reaction






47. 1.66 x 10^-24 g






48. Positive charged ions






49. When elements from two different compounds didsplace each other to form new compounds - like when solutions of CaCl and HgNi combine to form insoluble HgCl and CaNi






50. The decay of a nuclei which results in the emission of certain particlces
