Pre - AP Chemistry

Subjects : pre-ap, science
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 14 elements with the atomic numbers 90-103.






2. The suborbitals of an atom. (S - P - D - F)






3. The state of matter in which the substance has definite volume and definite shape






4. A ratio derived from the equality between two different units that can be used to convert from one unit to the other






5. A form of energy that exhibits wavelike behavior as it travels through space (3.00x108 m/s)






6. A property that does not depend on the amount of matter present






7. A measure of the amount of matter






8. Emission of electrons from a metal when light shines on a metal.






9. The emission of a continuous range of frequencies of electromagnetic radiation.






10. Orbitals of equal energy are each occupied by one electron before any orbital is occupied by a second electron - and all electrons in singly occupied orbitals must have the same spin state.
