Covalent Bonds. Covalent bond: bond in which one or more pairs of electrons are shared by two atoms. Covalent bonding occurs when two (or more) elements .

Ionic Bonding: complete transfer of 1 or more electrons from one atom to another. (metals and non-metals). Covalent Bonding: valence electrons shared. Chemical Bonds – atoms combine, Electron distribution changes Ionic Bonds is the transfer of electrons (ex. salts, crystals) and is composed of a positive. There are three types of strong bonds: – Ionic. – Covalent. – Metallic. ○ Some substances contain both covalent and ionic bonding or an intermediate.

The atomic theory is the premise for the concept of chemical bonds. modern theory of chemical bonds, although it was a theory concerning chemical reactions . Chemical bonds make atoms more stable than they are if non-bonded. ▫ Bond formation involves changes in the electrons on two atoms. ▫ Electron transfer. shared by atoms to form chemical bonds. Write a sentence comparing household glue to chemical bonds. Science Journal. Atomic Structure and Chemical. Chemical Bonding. • Materials → Molecules → Atoms. • Atoms = protons (p) + neutrons (n) + electrons (e). • Protons and neutrons are made of quarks. Covalent Bonds. Covalent chemical bonds involve the sharing of a pair of valence electrons by two atoms, in contrast to the transfer of electrons in ionic bonds.
