Atomic Diagrams Assignment Instructions SAMPLE PROBLEM: Draw an energy level diagram for the element. magnesium Draw an electron dot diagram for the element listed above. Step 1: Find magnesium on your periodic table of the elements. Step 2: Print the symbol in the center of the box. 1 1 IA 1 1 2 2 IIA 3 4 5 <<<<<<<<< H 1.00794 Mg hydrogen 2 3 4 Li Be 6.941 lithium Step 3: Determine the number of energy levels in the atom by looking at which period it is in. Then, draw in the same number of energy levels as the period number Mg 3 4 9.0122 beryllium 11 12 Na Mg 22.99 24.3050 sodium magnesium IIIB IVB VB 23 19 20 21 22 K Ca Sc Ti V 39.098 40.0800 44.956 47.88 50.94 potassium calcium scandium titanium vanadium Energy Level Rules 1st energy level – maximum of 2 electrons 2nd energy level – maximum of 8 electrons outside energy level - maximum of 8 electrons Step4: Finally, place dots on the energy levels to represent the appropriate number of electrons according to the rules stated in this box. Mg Step 5: Print the element symbol Place dots for each “valence” electron around the symbol. (Valence electrons are the electrons in the outside energy level.) Note: It is customary to place the dots in pairs around the symbol. Finished electron dot diagram for magnesium Mg Atomic Diagrams Assignment Name 1. In the boxes below, draw a energy level diagrams for the following elements. carbon beryllium neon argon phosphorus fluorine boron hydrogen sodium aluminum chlorine silicon nitrogen sulfur Your diagram must show the arrangement of all of the electrons in the atom. Print the element symbol in the center of the diagram. Example: Mg 2. In the boxes below, draw electron dot diagrams for each of the elements listed in #1. Print the element symbol in the center of the diagram. Mg
