Classroom Resources: Chemistry Basics

1 – 5 of 5 Classroom Resources

• 

  Atomic Radius, Ionic Radius, Electrons, Model of the Atom, Subatomic Particles, Periodic Table | Elementary School, Middle School, High School

  Animation: Atomic & Ionic Radii Animation

  This animation explores patterns in atomic and ionic radii. Students will look at the different sizes of atoms in the third period and the atoms in the sixth group to see trends across periods and down groups. They will also look at an atom and its corresponding cation as well as an atom and its corresponding anion. **This video has no audio**

• 

  Model of the Atom, Electrons, Electron Configuration, Quantum Numbers, Subatomic Particles, Periodic Table | High School

  Animation: Orbitals Animation

  This animation explores the shapes of the 1s, 2s, 2p, 3s, 3p, 4s, and 3d orbitals and how they build up and overlap as each successive orbital is added. **This video has no audio**

• 

  Electron Affinity, Atomic Radius, Ionic Radius, Ions, Atoms, Periodic Table, Model of the Atom, Subatomic Particles, Electrons, Valence Electrons | High School

  Simulation: Periodic Trends II: Electron Affinity, Atomic Radius & Ionic Radius

  The May 2016 simulation is a follow-up to the March 2016 simulation. Students will focus their investigation on the electron affinity of an atom. Through the use of this simulation students will have the opportunity to examine the formation of an anion as well as compare the atomic radius of a neutral atom to the ionic radius of its anion.

• 

  Atomic Radius, Ionic Radius, Ionization Energy, Valence Electrons, Periodic Table, Atoms, Electrons, Subatomic Particles, Ions, Model of the Atom | High School

  Simulation: Periodic Trends: Ionization Energy, Atomic Radius & Ionic Radius

  In this simulation for the March 2016 issue, students can investigate the periodic trends of atomic radius, ionization energy, and ionic radius. By choosing elements from the periodic table, atoms can be selected for a side by side comparison and analysis. Students can also attempt to ionize an atom by removing its valence electrons. Quantitative data is available for each periodic trend, and can be further examined in a graph.

• 

  Intermolecular Forces, Polarity, Molecular Motion, Intermolecular Forces, Molecular Motion, Physical Change, Physical Change | High School

  Simulation: Comparing Attractive Forces

  In the November 2014 issue, students explore the different attractive foreces between pairs of molecules by dragging the "star" image. In the accompanying activity, students investigate different types of intermolecular forces (London dispersion and dipole-dipole). In the analysis that follows the investigation, they relate IMFs (including hydrogen bonding) to physical properties (boiling point and solubility).
