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






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






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






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






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






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






7. Components made up of a combination of atoms






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






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






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






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






12. The number of protons/electrons within an atom






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






14. Negative charged ions






15. 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






16. The degree that two liquids can mix together






17. Radioactive decay in which half of a sample decays






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






19. The conversion of liquid into a gas






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. Ammonia






22. The smallest form of a particle






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






24. Hydrocarbons that include carbon - carbon triple bonds






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






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






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






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






29. Hydrochloric acid






30. Sodium






31. 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






32. 1.66 x 10^-24 g






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






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






35. Water






36. Hydrocarbons that involve carbon - carbon double bonds






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






38. The conversion of a gas back into a liquid






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






40. Positive charged ions






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






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






43. The process of balancing chemical equations






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






45. A specific type of double deplacement when an acid reactts with a base to form salt and water






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






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






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






49. The transition from a gas into a solid






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