Tenth Grade Chemistry - Learning about Chemistry

Video 15-Molecular Geometry & Polarity introduces the idea of polarity - bond and molecular, and the influence of geometry on determining the overall polarity.

Video 14: Covalent Bonding & Molecular Geometry will help students understand how the repulsion between electron pairs around the central atom of a molecule dictates the geometry of the molecule. This will have important influence on the polarity of t ...

Video 13: Covalent Bonding & Naming will continue to explain the sharing of valence electrons between atoms and how compounds can be represented and named.

Video 12: Covalent Bonding covers an introduction to the idea of sharing of valence electrons by atoms in order to fulfill their valence shells. Their properties are also explored.

Video 11: Ionic Bonding - A Deeper Look focuses on the concept of ionic bonding and making ionic compounds. Students will learn how to write binary ionic compounds as well as polyatomic ionic compounds. In addition, students should be able to name them and write simple balanced equations for binary ionic compounds.

Video 10: The Periodic Table and Group Properties is an introduction to the idea of periodic trends and allows students to be able to predict the chemical properties of elements in groups 1 (Alkali Metals), 2, (Alkaline-Earth Metals), 7 (The Halogens) and 8 (The Noble Gases) based on group properties and their trends. In addition, students should be able to determine the number valence electrons and charge of the ions that elements in the main groups of the periodic table will form.

Video 9: "Classification of Elements - Part 2: The Periodic Table" covers the development of the Periodic Table by Mendeleev based on chemical properties and organized by atomic masses. The improvements made by Moseley (ordered the elements by atomic number) and Seaborg, (defining groups based on their electronic configurations) allows to understand the Modern Periodic Table and its structure.

Video 8: "Classification of Elements - Part 1: Early attempts" focuses on different ways in which elements can be classified, including physical state, and whether they are metals or non-metals. In each case, students will detail the characteristics of ...

Video 7: Orbitals and the Auf Bau Principle introduces students to the concept of orbitals, energy sub-levels in the principal quantum energy levels and the fine structure of electronic configurations. Students will be able to produce electronic configurations for atoms using the Auf Bau principle, in which electrons fill orbitals in order of increasing energy.

Video 6: Bohr & the Light Spectrum tackles the the emission spectra (and absorption, briefly) produced by excited atoms and serves as an introduction to Bohr's Quantized Atomic Model. Bohr's key points on atomic structure and energy levels are covered ...

This video will help students understand more about how the composition of the atom forms specific atomic species: elements, neutral atoms, ions and isotopes. In addition, they will learn how to calculate the relative atomic mass of elements based on their natural percent abundances.

Following Rutherford's Gold Foil experiment, students should be able to reach his conclusions about the atom and explain how they got there. In addition, students should be able to write symbols for atomic species based on protons, neutrons & electrons.

This video will take you from the Dalton atomic model to Thomson's Plum Pudding model.

This video explores Dalton's atomic theory and its postulates, while identifying the major problem with the theory and sets up the stage for the discovery of subatomic particles.

This video will guide the students from the beginnings of the idea of the atom in ancient Greece to developments of Modern Chemistry in 18th Century France. Lavoisier and Proust set the foundations for the rediscovery of atomic theory.
