    of reaction of Alkali metals and Alkaline Earth meatals are compared in this lab. The pH of each of the resulting metal solutions are tested and the products of the reaction between calcium and water is discovered. The tested elements are sodium‚ lithium‚ potassium and calcium and each of them were placed in a beaker filled with water. The resulting solutions pH levels were tested with litmus paper. There were more steps for caclium because it is the only Alkaline Earth metal. For calcium‚ the gas

    A metal is a solid material which is either an element‚ a compound or an alloy. Metals share some common properties like being typically hard and shiny‚ and that metals are good electrical and thermal conductors. They are generally malleable‚ fusible and ductile. In a periodic table of elements‚ there are six groups of metals and two of them are the most common. It is the Alkali Metals and the Alkaline Earth Metals. Alkali metals comprise the group 1 elements. They are similarly shiny‚ soft

    Objectives To study the quantitative relationship between the amount of reactants and products of a reaction ( that is how many moles of A react with a given mol of B). A known starting mass of magnesium and the measured collection of hydrogen gas will be used to determine the reaction stoichiometry and the valency of magnesium Introduction Stoichiometry is the study of the quantitative relationship between amounts of reactants and products of a reaction. Stoichiometry can be used to calculate the

    In this experiment‚ we used acquired observational data to develop an activity series describing the relative reactivity of the metals being tested. The elements within a periodic table often show different trends in physical and chemical properties depending on the period or group they are apart of. In a periodic table‚ elements are arranged by increasing atomic number in horizontal rows called periods. The atomic numbers represent the number of protons in each element. The periodic table is also

    an irritant. Group 2 elements Calcium Strontium Magnesium Beryllium Barium Radium Introduction: The Group 2 elements are all metals with a shiny‚ silvery-white colour having 2 electrons in their outermost shell. The alkaline earth metals are high in the reactivity series of metals‚ but not as high as the alkali metals of Group 1. The metals of Group 2 are harder and denser than sodium and potassium‚ and have higher melting points. These properties are due largely to the presence of
