Chemistry 6.0 Name_______________________________ Electrons The Periodic Law Fill in the blank with the appropriate answer: Period 4, 6 element Period 6 alkali metal period 3 metalloid A gas that typically forms ions with a charge of −2 period 5 halogen the family of elements that form diatomics group 16, period 5 used in bulb filaments, this element has similar properties to molybdenum a metalloid with 5 valence electrons with a tendency to gain electrons. an unreactive period 4 element The transition with the lowest atomic number a period 2 metal that forms oxides of the general formula M2O the family of nonmetals that has all states of matter represented the family of elements that do not typically form ions the family of elements that react with O2 in a 2 to 1 mole ratio the metal with the smallest atomic mass the series of elements that contains mendelevium the number with seven valence electrons the family name of elements that form +1 ions group 13 metalloid Write balanced equations for the reactions of each of the first three alkali metals with water. What do these elements have in common that result in these similar reactions? Write balanced equations for the electrolytic decomposition of the oxides of the first three alkaline earth metals. What do these elements have in common that result in these similar reactions?
