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 transition from a gas into a solid






2. Radioactive decay in which half of a sample decays






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






4. Sodium






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






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






7. Anything that has mass and takes up space






8. The number of protons/electrons within an atom






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






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






11. The smallest form of a particle






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






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






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






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






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






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






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






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






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






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






22. Ammonia






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






24. 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






25. The conversion of liquid into a gas






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






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






28. Organic compounds that contain nitrogen - including protein






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






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






31. 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






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






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






34. 1.66 x 10^-24 g






35. Negative charged ions






36. The conversion of a gas back into a liquid






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






38. The degree that two liquids can mix together






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






40. 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






41. Components made up of a combination of atoms






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






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






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






45. The process of balancing chemical equations






46. Water






47. Metals that have low melting points






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






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






50. Positive charged ions
