This document provides an assessment for students to write the electron configurations and draw Bohr diagrams for various elements. Students are given the element symbol, atomic number, and asked to write the electronic configuration and draw a Bohr diagram for 20 different elements ranging from hydrogen to calcium. The assessment is intended to test students' understanding of writing electron configurations and representing atoms using Bohr diagrams.
