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






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






3. Components made up of a combination of atoms






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






5. The degree that two liquids can mix together






6. The conversion of liquid into a gas






7. 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






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






9. The smallest form of a particle






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






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






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






13. Hydrocarbons that include carbon - carbon triple bonds






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






15. The number of protons/electrons within an atom






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






17. Metals that conduct electricity






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






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






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






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






22. Organic compounds that contain nitrogen - including protein






23. Positive charged ions






24. 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






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






26. The transition from a gas into a solid






27. The process of balancing chemical equations






28. The conversion of a gas back into a liquid






29. An atom that has an electrical charge






30. Radioactive decay in which half of a sample decays






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






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






33. Water






34. Hydrocarbons that involve carbon - carbon double bonds






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






36. Anything that has mass and takes up space






37. Metals that have low melting points






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






39. 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






40. 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






41. Sodium






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






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






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






45. Hydrochloric acid






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






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






48. Ammonia






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






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