CHEMISTRY 101 ACTUAL TEST SCRIPT WITH
SOLVED QUESTIONS AND VERIFIED
ANSWERS
●● periodic table
Answer: an arrangement of elements in which the elements are separated
into groups; used to what elements might combine with other elements
and find similar elements
●● The literal meaning of atom is
Answer: uncuttable
●● What is the lightest element?
Answer: Hydrogen
●● law of definite proportions
Answer: a chemical compound contains the same elements in exactly the
same proportions by mass regardless of the size of the sample or source
of the compound
●● Antoine Lavoisier
Answer: discovered law of conservation of mass, helped create the
metric system and was murdered by French revolutionaries
, ●● Electrolysis
Answer: A process by which an electric current breaks chemical bonds.
●● John Newlands (1864)
Answer: -Noticed that the elements showed repeating properties when
arranged by atomic mass.
-Every 8th element, patterns repeated. He named it the Law of Octaves.
●● Michael Faraday
Answer: English chemist who created the first simple electric motor and
the first dynamo; known as the best experimental scientist
●● Dmitri Mendeleev
Answer: Father of the periodic table
●● Electron
Answer: negatively charged particle
●● cathode ray tube
Answer: evacuated glass tube in which a stream of electrons emitted by
a cathode strikes a fluorescent material, causing it to glow; examples
would be neon lights, fluorescent lights and old tv tubes
