Ionic Bond – NaCl
Ion Atoms are made up of an atomic nucleus and electrons. Electrons far from the atomic nucleus may easily fall off, or electrons from outside may enter. If a neutral atom loses…

Covalent Bonds of Hydrocarbon
When atoms combine to form molecules, atoms generally each lose, gain, or share valence electrons until they attain or share eight. A valence electron is the outer shell electron that is associated…

Ion Model (Whiteboard)
You can create ionic compounds by dragging and dropping atoms. Ion fragments that are no longer needed can be returned to their original location.
Making Molecular Models (Whiteboard)
You can create molecular structures by dragging the atoms. Atoms that no more needed can be returned to the periodic table.
Ionic Bond
Formation and energy of the ionic bonds Metal atoms have strong properties to lose electrons and become cations. On the contrary, non-metallic atoms have strong properties to obtain electrons and become anions.…

Covalent Bond
What is Covalent Bond? The covalent bond is a bond formed by atoms. Each atom creates an electron pair and shares it. Because each other’s electrons are shared in pairs, the number…
