Ionic bonding

Ionic bonding, also called electrovalent bond, is an electrostatic attraction between negatively charged ions in a chemical compound. This bond forms the outer shell electrons of one of the atoms to get transferred to another one permanently. Properties of ionic compounds - Ionic compounds have high melting and boiling point - They are tough but fragile - They are soluble water but insoluble in organic solvents - They conduct electricity when dissolved in water or when melted

Covalent bonding Covalent bonding is when 2 atoms pair between each other and there the same amount of atoms to stabilise. There are 3 types of covalent bonds, double covalent bond and triple covalent bond. For Example: Water (H2O) Carbon Dioxide (CO2) Hydrogen chloride (HCI) Hydrogen fluoride (HF)

Properties of simple covalent molecules - Low melting point - Low boiling point Properties of giant covalent structures - Solid at room temperature - High boiling point - High melting point - They are very strong - A lot of energy is needed in order to break up those large structures during the melting and boiling. Do not conduct electricity

How do atoms bond in metals? Metals from giant structure in which the outer shell electrons move freely, the metallic bond is the force of attraction between the free electrons and the positive ions.

How metallic bonding allows metals to conduct electricity? These metals conduct electricity of their free electrons, and the metallic bonding is unique because the electrons are not bounding to a specific atom, It helps the delocalised electrons to find a potential difference.
