Electron configuration lab answers. Practice: Determine the electron configurations of the following elements. How many protons, neutrons, and electrons are in atoms of these isotopes? Write the complete electron configuration for each isotope. If your periodic table doesn’t agree with this, your answers for elements near the f-orbitals may be slightly different. They will also examine relationships between electron configurations and chemical properties. Spdf Orbitals - Google Search - Free download as PDF File (. During this lab the students will follow the individual and group directions to answer different questions related to the Periodic Table an Electron Configurations - Solutions Note: The electron configurations in this worksheet assume that lanthanum (La) is the first element in the 4f block and that actinium (Ac) is the first element in the 5f block.
