Sodium Alkali Metal Barium Alkaline Earth Metal Cobalt Transition Metal Bromine Halogen Xenon Nobel Gas Germanium Metalloid Uranium Actinide True or False.Hydrogen is an alkali metal because it is in group 1. True False True or False.Helium has 8 valence electrons because it is a noble gas. True False Fill in the table. For each element, indicate how many valence electrons it has. Element Number of Valence Electrons Strontium 2 Aluminum 3 Sulfur 6 Cesium 1 Fill in the table. Each of the following elements will either lose or gain electrons to become cations or anions. Complete the table by filling in each column. You must put the sign (+ or -) for the charges. Element Gain or Lose Electrons Cation or Anion? Charge Lithium Lose Cation +1 Chlorine Gain Anion -1 Iron Loses 3 electrons Cation +3 Nitrogen Gain Anion -3 What group of elements lose different amounts of electrons, resulting in various charges of cations?
