It has a melting point of 650°c and a boiling point of 1091°c. It is located in Group 2 as a metallic solid at room temperature it is relatively light weight and strong. Ionization potential: 80.143 eV Oxidation states: 2 Electrical conductivity: 0. Magnesium was identified by Joseph Black in 1755 who identified it as an element but it was not until 1808 when Sir Humphrey Davy used electrolysis to separate Magnesium metal from Magnesium oxide. Magnesium (Mg) 12 Chemical Element Periodic Table Go to element Physical data Electronic data Shells: 2, 8, 2 Orbitals: Ne 3s 2 Electronegativity: 1.2, 1.2 1. Magnesium is also important in the growth of plants as its role in the central metal of chlorophyll, the site of photosynthesis. You can use this chart to predict whether or not an atom can bond with another atom.The charge on an atom is related to its valence electrons or oxidation state.An atom of an element is most stable when its outer electron shell is completely filled or half-filled. The values mentioned in the chart are given in electron. This is a chart of the most common charges for atoms of the chemical elements. Note: The ionization energy is measured in joules (J) or electron volts (eV). First ionization energy, second ionization energy as well as third ionization energy of the elements are given in this chart. 12 Mg Group 2 Period 3 Block s Protons Electrons Neutrons 12 12 12 General Properties Atomic Number 12 Atomic Weight 24. It also has common uses as an antacid in its compound of Magnesium hydroxide. Ionization energy chart of all the elements is given below. Magnesium is commonly used in flares and fireworks due to the bright white flame produced upon its combustion. It is a shiny silver coloured metal but often has a dull appearance due to tarnishing by its reaction with Oxygen to form Magnesium oxide. Magnesium is located in the Alkaline earth metals, Group 2. It is an Alkaline Earth Metal and is located in Group 2 of the periodic table, it has the symbol Mg. Magnesium (Mg) is a silver coloured metal that has the atomic number 12 in the periodic table.
