The Valence Shell Electron Pair Repulsion (VSEPR) theory predicts molecular shapes by focusing on the repulsion between electron pairs surrounding a central atom. The main postulates include: Electron Pair Repulsion: Electron pairs...

VSEPR postulates state that the geometry of a molecule depends on the number and arrangement of bonding and lone electron pairs around the central atom

Struggling with VSEPR theory and molecular geometry? This video simplifies the concepts you need to master these essential chemistry topics. Learn how to draw Lewis structures with the correct geometry, understand bond angles, and...

It describes electronic configuration of the elements of group 14, their physical, chemical properties and their uses.

What's with all these shapes? Let's practice assigning hybridization, electron-domain geometry, and molecular geometry. Octahedral! Tetrahedral! Linear! Pyramids and see-saws and what not! Chemistry is fun, isn't it?

Silicates are a particularly complex class of minerals that all contain silica tetrahedra. What are the characteristic structures of the last three sub classes of silicates? How are they different from one another?

Crystal Field Stabilization Energy (CFSE) 5: Tetrahedral High-Spin

We are used to using a theory like VSEPR theory to predict molecular geometry, but unfortunately with coordination compounds, things are not so simple, because of those pesky d orbitals on the central metal atom. Crystal field theory is...

Did you know that geometry was invented by molecules? It's true! Until the first stars went supernova and littered all the elements across the cosmos, everything was simply spheres, from protons to stars. But then, under cooler planetary...
