Atomic Number = 36 Neutrons = 48 What is ionization energy? The amount of energy needed to remove an electron from an atom Red Light has a ____ wavelength and a _____ frequency compared to Violet light Long Wavelength Low Frequency Does Bromine Gain or lose electrons? Is it a metal, nonmetal, or metalloid? Gains electrons and becomes negative in charge Nonmetal This “effect” causes atoms on the bottom of the periodic Table to have a small ionization energy What is the shielding effect? The model of “atomos” was used by which scientist(s) Who was Democritus and Dalton? nd 2 The law of this scientist was changed with the discovery of subatomic particles ie. Protons, neutrons, and electrons Who was Dalton? Which scientist had an atomic model with a positive Nucleus and a Negative electron cloud making up the majority of their space Who was Rutherford? Hydrogen was electrified to observe electrons jumping energy levels Who was Niels Bohr? Draw and label Thomson’s model of the Atom The plum pudding model A positively charged ball with negatively charged electrons This family has two valence electrons. What are the Alkaline Earth Metals? Silicon shares, rather than loses or gains, electrons. What is a Metalloid? This family is the entire d Block What are the Transition Metals This family has valence electrons that are s2p5 What are the Halogens? This is a family of nonreactive gasses What are the noble gasses? The plateau during the heating of a solid pure substance represents… The Melting Point The point at which both solids and liquids are found A gas evolves with a strong odor from two chemicals being mixed. There is a lot of heat produced What is an exothermic chemical change These letters represent the heating of the solid What is A-B Calculate the Atomic Mass of Copper Given the following info. Cu 63.0 has an abundance of 69.2% Cu 65.0 has an abundance of 30.8% Sig Figs and Units!!!!! Copper’s Atomic Mass 63.6 amu You need to include amu to be correct!! Sig Figs!!!! What does mass measure? The amount of matter in a substance What truly determines if an atom is a metal? Low ionization energy and a large atomic radius The Lewis Dot Structure for Aluminum . .Al. What is the Electron Configuration and Lewis Dot Structure for Tin Use both long hand and nobel gas configuration Sn: 1s22s22p63s23p64s23d104p65s24d105p2 Sn: [Kr] 5s24d105p2 Why don’t we draw a Bohr model for Titanium? Titanium is in the d-block. Bohr models stop at Ca. The 3d electrons go back to the third energy level rather than continuing on the 4th energy level If You remove an electron from Potassium, how many Valence electrons does it have? Why would potassium lose an electron? Eight Potassium lost one valence to have the same electron configuration as Argon, thus having eight electrons.
