Froggy Jumps Periodic table organization (6.1)Online version history of the periodic table and general classifications by Sheri Prosperi 1 Element were originally organized by a properties b atomic number c atomic mass 2 Mendeleev organized his periodic table with increasing a atomic number b atomic mass c properties 3 The modern periodic table is organized with increasing a properties b atomic mass c atomic number 4 The three broad classes of elements are a metals, nonmetals, and metalloids b heavy metals, light metals, and sortof metals c metallic, malleable, and ductile 5 The elements with similar physical and chemical properties are a carbon and boron b oxygen and nitrogen c chlorine and bromine 6 The elements with similar physical and chemical properties are a oxygen and nitrogen b carbon and boron c strontium and magnesium 7 The elements with similar physical and chemical properties are a sodium and magnesium b calcium and beryllium c potassium and calcium 8 The elements with similar physical and chemical properties are a nickel and niobium b nitrogen and neon c sodium and cesium 9 The elemental class that gold belongs to is a metalloids b metals c nonmetals 10 The elemental class that silicon belongs to is a metals b metalloids c nonmetals 11 The elemental class that sulfur belongs to is a nonmetals b metalloids c metals 12 The elemental class that barium belongs to is a metalloids b nonmetals c metals 13 The element that helped support Mendeleev's periodic table a germanium b cadmium c gallium 14 The pattern that is revealed when elements are arranged in a periodic table in order of increasing atomic number is a chemical reaction and identification repetition b solid and liquid property repetition c physical and chemical property repetition 15 The element with similar properties as carbon is a zinc b silicon c bismuth 16 The classification with the characteristics of being a gas at room temperature is a metals b metalloids c nonmetals 17 The classification with the characteristics of being brittle is a metalloids b nonmetals c metals 18 The classification with the characteristics of being malleable is a metals b nonmetals c metalloids 19 The classification with the characteristics of being a poor conductor of electrical current is a metalloids b metals c nonmetals 20 The classification with the characteristics of being shinny is a metals b nonmetals c metalloids
