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






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






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






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






5. Ammonia






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






7. The conversion of liquid into a gas






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






9. The smallest form of a particle






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

16. Anything that has mass and takes up space






17. The transition from a gas into a solid






18. The process of balancing chemical equations






19. 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






20. An atom that has an electrical charge






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






22. 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

30. Metals that have low melting points






31. Organic compounds that contain nitrogen - including protein






32. Metals that conduct electricity






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






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






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






36. The outer electron in a shell






37. Hydrocarbons that involve carbon - carbon double bonds






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






39. Hydrochloric acid






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






41. The degree that two liquids can mix together






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

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






46. The conversion of a gas back into a liquid






47. 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






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






49. The number of protons/electrons within an atom
