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. Anything that has mass and takes up space






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






3. Radioactive decay in which half of a sample decays






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






5. 1.66 x 10^-24 g






6. Organic compounds that contain nitrogen - including protein






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






8. 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






9. An atom that has an electrical charge






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






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






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






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






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






15. Hydrocarbons that involve carbon - carbon double bonds






16. Metals that have low melting points






17. 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






18. The smallest form of a particle






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






20. Metals that conduct electricity






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






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






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






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






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






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






27. Negative charged ions






28. Components made up of a combination of atoms






29. Water






30. The degree that two liquids can mix together






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






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






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






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






35. Hydrochloric acid






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






37. The transition from a gas into a solid






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






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






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. The conversion of liquid into a gas






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






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






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






45. The outer electron in a shell






46. The process of balancing chemical equations






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






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






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






50. Hydrocarbons that include carbon - carbon triple bonds
