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






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






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

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






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






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






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






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






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






15. Metals that conduct electricity






16. Components made up of a combination of atoms






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






18. The smallest form of a particle






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

23. Water






24. Positive charged ions






25. Ammonia






26. An atom that has an electrical charge






27. 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






28. Organic compounds that contain nitrogen - including protein






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






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

35. Anything that has mass and takes up space






36. 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






37. Negative charged ions






38. Radioactive decay in which half of a sample decays






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






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






41. The degree that two liquids can mix together






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






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






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






45. The outer electron in a shell






46. Hydrocarbons that include carbon - carbon triple bonds






47. The number of protons/electrons within an atom






48. 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






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






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