You will be introduced to the concept of atoms sharing electrons to form covalent bonds, and you will construct models of molecules with covalent bonds.
After completing this tutorial, you will be able to complete the following:
This Activity Object explores covalent bonds, a term used to describe the bonds that result from the sharing of one or more pairs of electrons. An atom contains a core called a nucleus, and the nucleus contains minute particles called protons and neutrons. The nucleus is surrounded by a cloud of electrons. Sometimes when two atoms join, two or more electrons are shared by the nuclei of both atoms. The atoms become bound together by this sharing of electrons.
Atoms must contain a certain number of electrons to be stable. One way for atoms to have the stable number of electrons is to share electrons. Sharing electrons forms a chemical bond between the atoms that is called a covalent bond. The structures that are formed by covalent bonding are called molecules. Each molecule has a fixed formula and a fixed alignment.
