Use the periodic table to predict the valence electron configuration of all the elements of group 2 (beryllium, magnesium, calcium, strontium, barium, and radium). Learn how to use an element's position on the periodic table to predict its properties, electron configuration, and reactivity. It is the basic ordering principle of the periodic table. Strategy: Identify the block in the periodic table to which the group 2 elements belong. Asked for: valence electron configurations. }, {AtomicRadius, ScatterPlot, False, The calculated distance from the nucleus to the outermost electron. Given: series of elements. Asked for: valence electron configurations. Use the periodic table to predict the valence electron configuration of all the elements of group 2 (beryllium, magnesium, calcium, strontium, barium, and radium). An up-to-date periodic table with detailed but easy to understand information Color of the element symbol shows state of matter: black=solid: white=liquid Strategy: Identify the block in the periodic table to which the group 2 elements belong. To write electron configuration of an element, locate its symbol in ADOMAH Periodic Table and cross out all elements that have higher atomic numbers. For example, if you need to write electron configuration of Erbium (68), cross out elements 69 through 120. Electron configuration of every element in the periodic table # Element Electron configuration 1 Hydrogen 1s1 2 Helium 1s2 3 Lithium 1s22s1 4 Beryllium 1s22s2 5 Boron 1s22s22p1 6 Carbon 1s 22s22p 7 Nitrogen 1s 22s 2p3 8 Oxygen 1s22s22p4 9 Fluorine 1s22s22p5 10 Neon 1s22s22p6 11 Sodium 1s22s22p63s1 12 Magnesium 1s22s22p63s2 13 Aluminum 1s 22s 2p63s 3p1 14 Silicon … This periodic table contains each element's atomic number, atomic mass, symbol, name, and electron configuration. Elements that appear below the main body of the periodic table; Lanthanides and Actinides; Electron configuration has the outer s sublevel full, and is now filling the f sublevel Orbitals The regions around the nucleus of an atom where there is a high probability of finding an electron; holds up to 2 electrons Explore the Bohr model and atomic orbitals. Electron Configuration of the elements. • The knowledge of the location of the orbitals on the periodic table can greatly help the writing of electron configurations for large atoms. cool periodic table with electron configuration. Given: series of elements. ELECTRON CONFIGURATION AND THE PERIODIC TABLE • The electrons in an atom fill from the lowest to the highest orbitals. The electron configurations are written in the noble gas notation.
