Description

Valence Shell Electron Pair Repulsion (VSEPR) models illustrate molecular geometry, resonance, and molecule polarity.

VSEPR 1 model supports students' investigation of the octet rule to create models of molecules with linear, tetrahedral, pyramidal, bent, and trigonal planar shapes.
Model includes:

• Two carbons
• Four oxygens
• Five hydrogens
• Three halogens
• Three nitrogens
• Two sulfurs
• Six short tubes
• Six long tubes

VSEPR 2 model helps students understand exceptions to the octet rule. Students will create octahedral, square planar, trigonal, hipyramidal, trigonal planar, linear, and bent molecules.
Model includes:

• 2-2 trigonal bipyramidal
• Two octahedral
• Five oxygens
• Three hydrogens
• Seven halogens
• Two nitrogens
• Eight short tubes
• Eight long tubes
