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. Small component of an atom that has no electrical charge






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






3. 1.66 x 10^-24 g






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






5. The conversion of liquid into a gas






6. Hydrocarbons that include carbon - carbon triple bonds






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






8. Anything that has mass and takes up space






9. Positive charged ions






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






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






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






13. The smallest form of a particle






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






15. Sodium






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






17. Negative charged ions






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






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






20. The transition from a gas into a solid






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






22. An atom that has an electrical charge






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






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






25. 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






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






27. Organic compounds that contain nitrogen - including protein






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






29. Metals that have low melting points






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






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






32. Components made up of a combination of atoms






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






34. Water






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






36. The process of balancing chemical equations






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






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






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






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






41. 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






42. The degree that two liquids can mix together






43. Metals that conduct electricity






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






45. The conversion of a gas back into a liquid






46. Hydrocarbons that involve carbon - carbon double bonds






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






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






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






50. 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
