4.5 Physical properties of molecular covalent
... Covalent molecules are not charged because they are overall neutral and therefore do not conduct electricity. • Some covalent molecules can react with water and produce free ions which can carry an electrical current. • E.g. ammonia, NH3 NH3 (l) + H2O (l) ↔ NH4+ (aq) + OH- (aq) ...

Dissociation of a Diatomic Gas
... Let us consider the following simple model for a diatomic gas: a diatomic molecule consists of a pair of point-like atoms, each of mass m, separated by a rigid rod of length a. The rigid rod corresponds to the chemical bond, which requires an energy to break. Now, at any finite temperature T , we ...

Molecular Geometry Why?
... is based on the premise that electrons around a central atom repel each other. Electron domains are areas of high electron density such as bonds (single, double or triple) and lone-pairs of electrons. In simple terms VSEPR means that all electron bonding domains and electron nonbonding domains aroun ...
