Organic Chemistry, 8e (Wade) Chapter 1 Introduction and Review 1) While you were up late one night studying organic chemistry, you happened to see the last 5 minutes of an infomercial on TV. The spokesperson claimed that their brand of automobile tires were superior to all other brands on the market because they were made by using only natural rubber, isolated from the resin of rubber trees. How could a chemist test her claims that no petroleum products went into the manufacture of her bra...

Aufbau principle - -procedure in which the electron configuration of the elements is determined by "building" them in order of atomic numbers, adding one proton to the nucleus and one electron to the proper subshell at a time core electron - -electron in an atom that occupies the orbitals of the inner shells electron configuration - -electronic structure of an atom in its ground state given as a listing of the orbitals occupied by the electrons Hund's rule - -Every orbital in a subshell...

What consists of a small, positively charged nucleus surrounded by electrons? an atom What does a nucleus consist of? protons and neutrons Atomic number? the number of protons in the nucleus Mass number? the total number of protons and neutrons in the nucleus Isotopes? atoms of the same element that have the same atomic number (protons) but different mass numbers (neutrons) How to find average atomic mass? natural % abundance x mass (amu),of each isotope,...

Rutherford's Gold Foil Experiment correct answers proposed that atoms consist of a tiny, massive, positive nucleus surrounded by electrons nucleus correct answers contains all the positive charge and nearly all the mass of the atom James Chadwick correct answers discovered the neutron cathode rays correct answers move from negative electrode to positive electrode (like electrons in a voltaic cell) Thompson's Cathode Ray Experiment correct answers discovery of the electron (also the...
