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 decay of a nuclei which results in the emission of certain particlces






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






3. Organic compounds that contain nitrogen - including protein






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






5. 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






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






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






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






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






10. The outer electron in a shell






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






12. The process of balancing chemical equations






13. Metals that have low melting points






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






15. Hydrochloric acid






16. Components made up of a combination of atoms






17. The smallest form of a particle






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






19. 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






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






21. Hydrocarbons that include carbon - carbon triple bonds






22. 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






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






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






25. 1.66 x 10^-24 g






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






27. Water






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






29. 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






30. The transition from a gas into a solid






31. Anything that has mass and takes up space






32. The degree that two liquids can mix together






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






34. The conversion of a gas back into a liquid






35. Negative charged ions






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






37. Positive charged ions






38. Metals that conduct electricity






39. Sodium






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






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






42. Hydrocarbons that involve carbon - carbon double bonds






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






44. An atom that has an electrical charge






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






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






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






48. Radioactive decay in which half of a sample decays






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






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