WebbTetrahedral. Molecules with four bonded electron pairs and no lone pairs form a tetrahedral shape. This is a regular triangular-based pyramid. All the bond angles are 109.5°. For example, the carbon in methane C H 4 has four valence electrons, and each electron is part of a pair bonded covalently to a hydrogen atom. WebbMolecules are the simplest unit of a covalent compound, and molecules can be represented in many different ways. Atoms are the smallest units of matter that still retain the fundamental chemical properties of an element.

WebbThe shape of a covalent molecule can be predicted using the Valence Shell Electron Pair Repulsion (VSEPR) theory. Very simply, VSEPR theory says that the valence electron pairs in a molecule will arrange themselves around the central atom(s) of the molecule so that the repulsion between their negative charges is as small as possible.

WebbSHAPES OF MOLECULES AND IONS The shape of a molecule depends upon its electronic structure. It is the outer shell or valence shell electrons which are responsible for forming bonds and it is the arrangement of these electrons which determine molecular shape. The electrons are all negatively charged and so will repel each other.
