IPC practice test questions Periods - correct answer Each horizontal row of the periodic table. Groups / families - correct answer Each vertical column. Have similar chemical properties and similar electron configurations. Demitri Mendeleev - correct answer Made the first periodic table. He was writing a textbook and wanted to organize the 63 elements known at that time. He based his organization similar to the card game of solitaire. Increasing mass - correct answer Mendeleev organized his periodic table in horizontal rows in order of... Fluorine - correct answer The most active nonmetal. Right - correct answer Nonmetals are to the ________ of the zigzag line. Border - correct answer Metalloids _______ the zigzag line. Valence electrons - correct answer Are electrons found in the most outer or highest energy level. Left - correct answer Metals are to the ________ of the zigzag line. Metals - correct answer Most elements on the periodic table are ______. Group 1A - correct answer Has the most active metals. Transition metals - correct answer Form very colorful compounds. Rare earth elements - correct answer The _________ include the Lanthanide series and the Actinide series. Group 1A - correct answer The Alkali Metal Family. Have one valence electron and are very reactive. They are not found except in the form of compounds in nature. Group 2A - correct answer The Alkaline Earth Metal Family. Have two valence electrons. are harder than Group 1A. Melting point is higher. differences in reactivity are among alkaline earth metals are shown by the ways they react with water. Group 3A - correct answer The Boron Family. Have three valence electrons. Group 4A - correct answer The Carbon Family. Have four valence electrons. Life on earth would not exist without carbon. most compounds in your body contain carbon. familiar with carbon in the form of coal or a diamond. Group 5A - correct answer The Nitrogen Family. Have five valence electrons. 80% nitrogen is found in the air. Group 6A - correct answer The Oxygen Family. Oxygen is the most abundant element in the earths crust. it is necessary for life. the air we breath is 20% oxygen. Group 7A - correct answer The Halogen Family. Have seven valence electrons. The halogens are highly reactive nonmetals that react easily with metals. Group 8A - correct answer The Noble Gases. Helium has two valence electrons. the rest have eight (or an octet). All noble gasses are used in neon lights.
