There are three ways to indicate the arrangement of electrons around an atom: 1. Orbital Filling Diagram (gives the most information) Ex. O2 1s 2s 2p 2. Electron Configuration (quicker to draw than orbital filling diagrams) Ex. O2 1s 2s? 2p 3. Electron Dot shows only the valence (outer energy level) electrons Ex. Oxygen atom 1. Write orbital filling diagrams, electron configurations, and electron dot diagrams for the following elements. Table: Bect Dot Degram Element Orbital Filing Diagram Bectron Configuration a. Boron b. Silicon c. Sulfur d. Calcium e. lodine f. Rubidium g. Chromium h. Gallium

Crystal Structures

Solids are present all around us. They have different properties and applications. Diamond and graphite are two well-known solids. Diamond is the hardest material in the world and is used in making jewelry. Graphite on the other hand is soft. The lead of your pencil is graphite. Why are they so different in appearance and properties despite the fact they are chemically the same? Both are allotropes of carbon. The answer lies in the structure, the way constituent particles are arranged in the solids.
