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






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






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






4. The conversion of liquid into a gas






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






6. Ammonia






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






8. The process of balancing chemical equations






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






10. Components made up of a combination of atoms






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






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






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






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






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






16. 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






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






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






19. 1.66 x 10^-24 g






20. The degree that two liquids can mix together






21. Hydrocarbons that include carbon - carbon triple bonds






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






23. 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






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. Organic compounds that contain nitrogen - including protein






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






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






28. 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






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






30. The transition from a gas into a solid






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






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






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






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






35. The smallest form of a particle






36. Metals that conduct electricity






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






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






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






40. The number of protons/electrons within an atom






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






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






43. Hydrocarbons that involve carbon - carbon double bonds






44. Metals that have low melting points






45. Sodium






46. The outer electron in a shell






47. Negative charged ions






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






49. The conversion of a gas back into a liquid






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