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 smallest form of a particle






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






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






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






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






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






7. The outer electron in a shell






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






9. An atom that has an electrical charge






10. The conversion of liquid into a gas






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






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






13. 1.66 x 10^-24 g






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






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






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






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






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






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






20. 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






21. Organic compounds that contain nitrogen - including protein






22. Anything that has mass and takes up space






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






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






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






26. 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






27. Negative charged ions






28. Ammonia






29. Positive charged ions






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






31. Components made up of a combination of atoms






32. Water






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






34. The degree that two liquids can mix together






35. 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






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






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






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






39. Hydrochloric acid

48. Metals that conduct electricity






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






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