Science Curriculum Standards 3221 - Chemistry I	Internet Resources
Identify the contributions of major atomic theorists: Bohr, Chadwick, Dalton, Planck, Rutherford, and Thomson. 1.1
Compare the Bohr model and the quantum mechanical electron-cloud models of the atom. 1.2	The Bohr Model - proposed by Niels Bohr in 1915 The Bohr Model with a good animation The Rutherford Model The Cloud Model proposed by Erwin Schrödinger
Draw Bohr models of the first 18 elements. 1.3
Interpret a Bohr model of an electron moving between its ground and excited states in terms of the absorption or emission of energy. 1.4
Use the periodic table to identify an element as a metal, nonmetal, or metalloid. 1.5	Atoms: The Building Blocks of Matter - a 23 slide PowerPoint show Basic Building Blocks of Green Chemicals - from green chemistry and the ten commandments of sustainability - a 54-slide PowerPoint show Building Block Chemistry - The goal of Building Block Chemistry is to introduce students to chemistry without tackling the whole periodic table at once. Parts of an Atom and Organization of The Periodic Table - a 29 slide PowerPoint show plus nine assessment slides at the end of the show The Periodic Table and the Elements - a 19 slide PowerPoint show Periodic Tendencies -
Apply the periodic table to determine the number of protons and electrons in a neutral atom. 1.6
Determine the number of protons and neutrons for a particular isotope of an element. 1.7
Explain the formation of anions and cations, and predict the charge of an ion formed by the main-group elements. 1.8
Sequence selected atoms from the main-group elements based on their atomic or ionic radii. 1.9
Sequence selected atoms from the main-group elements based on first ionization energy, electron affinity, or electronegativity. 1.10
Determine an atom's Lewis electron-dot structure or number of valence electrons from an element's atomic number or position in the periodic table. 1.11	A handout to assist you in drawing Lewis structures A 31-question multiple choice practice quiz on Chemical Bonding (Lewis structures) [This quiz comes from the Internet Archive known as the Wayback Machine.] Confirming and visualizing Lewis Dot Structures - With this activity, students can calculate and visualize the atomic and molecular structures of bonds and lone pairs in the molecule methanol. Construct a Lewis Structure - Starting with a structure indicating only atom connections you can practice constructing a Lewis dot structure. Click on the atom or bond you wish to modify. How to draw a Lewis structure for a molecule The Lewis electron-dot symbols - focus on the electrons in the highest principal energy level in the atom, the valence electrons, the electrons that participate in chemical reactions Lewis Structures - atoms, ions, ionic compounds, and covalent compounds
Represent an atom's electron arrangement in terms of orbital notation, electron configuration notation, and electron-dot notation. 1.12
Compare s and p orbitals in terms of their shape, and order the s, p, d and f orbitals in terms of energy and number of possible electrons. 1.13	Atomic Orbitals - The table below contains links to VRML files depicting the isosurfaces for various atomic orbitals Atomic Orbitals - This page explains what an atomic orbital is. It explores s and p orbitals in some detail, including their shapes and energies Visualization of Atomic Orbitals - p Orbitals Visualization of Atomic Orbitals - s Orbitals
