WebC3.5 Molecules and covalent bonds. A covalent bond is formed by two NON-METAL atoms which combine together by sharing electrons. When two or more non-metal atoms are joined by covalent bonds we call them molecules. Summary: Ionic bonding-. Non-metal and metal. Electrons are lost or gained, the bond is a electrostatic force between opposite ions, WebExample Questions. Question 1: The most important covalent molecule on Earth is water, made up of one oxygen atom and two hydrogen atoms. Give the dot and cross diagram of a water molecule. Question 2: Covalent molecules can be represented using line diagrams or 3\text {D} models. Compare the contrast the two methods. ona bend st charles
