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






2. Water






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






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






5. The degree that two liquids can mix together






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






7. Positive charged ions






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






9. The smallest form of a particle






10. 1.66 x 10^-24 g






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






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






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






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






15. The conversion of a gas back into a liquid






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






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






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






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






20. Sodium






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






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






23. Hydrocarbons that involve carbon - carbon double bonds






24. An atom that has an electrical charge






25. The conversion of liquid into a gas






26. The outer electron in a shell






27. The transition from a gas into a solid






28. Hydrochloric acid






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






30. 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






31. Metals that conduct electricity






32. The number of protons/electrons within an atom






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






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






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






36. Components made up of a combination of atoms






37. Organic compounds that contain nitrogen - including protein






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






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






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. Metals that have low melting points






42. Hydrocarbons that include carbon - carbon triple bonds






43. Anything that has mass and takes up space






44. 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






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






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






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






48. Radioactive decay in which half of a sample decays






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






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