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. The degree that two liquids can mix together






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






3. The outer electron in a shell






4. Components made up of a combination of atoms






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






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






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






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






9. 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






10. Anything that has mass and takes up space






11. The smallest form of a particle






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






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






14. An atom that has an electrical charge






15. 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






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






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






18. The conversion of a gas back into a liquid






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






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






21. The process of balancing chemical equations






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






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






24. Positive charged ions






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






26. Water






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






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






29. Organic compounds that contain nitrogen - including protein






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






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






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






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






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






35. Hydrocarbons that involve carbon - carbon double bonds






36. 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






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






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






39. Sodium






40. The transition from a gas into a solid






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






42. Hydrocarbons that include carbon - carbon triple bonds






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






44. The number of protons/electrons within an atom






45. Metals that have low melting points






46. Hydrochloric acid






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






48. 1.66 x 10^-24 g






49. Radioactive decay in which half of a sample decays






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