Structure and bonding level 2

WebThe properties of elements can be generally explained in terms of electron occupancy at the highest energy level in the atom. These electrons are usually called valence electrons. ... then 2+ and 2- ions are formed. In such cases the bonding is called ionic bonding and the stability (lowered potential energy) is due to the mutual attraction ... Let's review the basics of chemical bonds including dot structures, hybridization, bond-line structures, electronegativity, and polarity. We will also discuss how bonding and intermolecular forces relate to physical properties such as boiling point. Dot structures Learn Dot structures I: Single bonds Dot structures II: Multiple bonds Hybridization

A water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent. This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons.
