'Diamond structure' presentation slideshows

Crystal structure of Diamond. Diamond structure is like a face-centered cubic(FCC) lattice. Each carbon atom joins four other carbon atoms in regular tetrahedrons. A tetrahedron has four faces and six edges. It is like an Egyptian pyramid in which the base is a triangle instead of a square. .

Basic Structure of Condensed Materials. Lecture 1. Outline. Motivation Atomic structure and interatomic bonding Crystalline materials Composite materials Soft materials (Polymers and Biomolecules) Magnetic materials Liquids and non-crystalline materials

Diamonds. DIAMONDS. WHAT DOES IT MEAN TO BE A DIAMOND?. Diamonds are unique. Diamonds come in all shapes and sizes . Diamond come in all c o l o r s : ……so be the Diamond you were meant to be……. Diamonds have extraordinary strength.

Diamonds. Diamond Structure & Bonding Structure : Giant covalent macromolecule Bonding : Each carbon atom has 4 bonding pairs of electrons and 0 lone pairs of electrons. According to VSEPR theory in order to minimize the repulsion the 4 pair of bonding electrons repel each other equally.
