Question Thirty One •Compare the size of a proton and a neutron They are about equal Question Thirty Two •Where is most of the mass of an atom located? nucleus Question Thirty Three •What charges do the three subatomic particles have? Proton is positive, Neutron is neutral and electron is negative Question Thirty Four •State the law of conservation of mass Matter cannot be created or destroyed – only conserved Question Thirty Five • If carbon reacts with oxygen to form carbon dioxide, and I have two grams of carbon and I make 12 grams of carbon dioxide, how much oxygen did the carbon react with? 10 Grams (law of conservation of mass) Question Thirty Six •Who was the Greek philosopher who made the first observations about the atom?

Electrons circle the nucleus in Energy levels Question Forty Six •How many protons, neutrons, and electrons are located 13 in this atom 6C? 6 protons, 7 neutrons, 6 electrons Question Forty Seven •How many protons, neutrons, and electrons are located 26 in this atom Mg? 12 protons, 14 neutrons, 12 electrons Question Forty Eight • Calculate the average 24 atomic mass: Mg 25 (78.99%) Mg (10.00%) 26Mg (11.01%) 24.3202 amu Question Forty Nine • Rubidium has two common isotopes. If the abundance 85 of Rb is 72.2% and the 87 abundance of Rb is 27.8%, what is the average atomic mass? 85.556 amu Question Fifty • Titanium has five common isotopes. 46Ti (8.0%), 47Ti 48 49 (7.8%), Ti (73.4%) Ti 50 (5.5%) Ti (5.3%). What is the average atomic mass? 47.923 amu Question Fifty One •What charge will an atom have if it loses two electrons? +2 Question Fifty Two •What charge will an atom have if it gains one electron? -1 Question Fifty Three •What is the name of the group that can either gain or lose four electrons? Carbon Family Question Fifty Four • What is the defining feature which distinguishes one element from another element? Number of protons (atomic number) Question Fifty Five •What are valence electrons? Electrons in the outermost energy level Question Fifty Six •What chemist designed the first periodic table? Mendeleev Question Fifty Seven •Write the isotope notation for an ion of Phosphorus with 16 neutrons 3115 P-3 Question Fifty Eight •How many electrons would an ion of tellurium have? 54 Question Fifty Nine • Which has a higher ionization energy, sodium or chlorine, why? Chlorine because it is in the same energy level as chlorine, but has more protons … so harder to remove an electron from it Question Sixty • Which has a larger atomic radius, lithium or rubidium? Why? Rubidium because more energy levels means electrons are found farther from nucleus – and therefore atom is bigger Question Sixty One • Which will have a higher melting point, chromium or neon? Why? Chromium because chromium is a solid at room temperature and neon is a gas at room temperature (chromium is a metal and neon is a nonmetal) Question Sixty Two •Which will have a greater density, gold or xenon? Why? Gold b/c gold is a metal (solid) and xenon is nonmetal (gas) Question Sixty Three • Which will have a higher electron affinity, calcium or arsenic? Why? Arsenic because it is in the same energy level and it has more protons – so it will release more energy when an electron is added Question Sixty Four • Which will have a higher ionization energy, oxygen or selenium? why? Oxygen because electrons are closer to nucleus due to less energy levels – so harder to remove the electron from the valence shell. Question Sixty Five • Which will have a larger atomic radius, carbon or fluorine? Why? Carbon will have a larger atomic radius because it is in the same energy level but has less protons – so less of a pull on the valence shell. Question Sixty Five and a Half •Write the shorthand electron configuration for lead [Xe]6s24f145d106p2 Question Sixty Six • Which will have a higher electron affinity, nitrogen or antimony? Why? Nitrogen because the electrons are closer to the nucleus since there are fewer energy levels – so the nucleus would be better able to hold onto an additional electron.
