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

22. An atom that has an electrical charge






23. Metals that have low melting points






24. 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






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

35. 1.66 x 10^-24 g






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






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






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






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






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






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