Why Ionic Bonds

are the way they are!

How bonds are formed...

High melting and boiling points because Ionic bonds are very strong.Ionic solids do not conduct electricity (they are insulators). This is because the ions are tightly packed together.When molten (liquid) ionic compounds conduct electricity.When dissolved in water to form a liquid solution ionic compounds conduct electricity because their ions are free to move around (Ionic Bonding).Are hard, brittle, and crystalized (Helmenstein).

Ionic substances form giant ionic molecules containing oppositely charged ions therefore, they have high melting and boiling points( since they are harder to break apart), and conduct electricity when melted or dissolved in water.Simple molecular substances consist of molecules in which the atoms are joined by strong covalent bonds. Their molecules are held together by weak forces, so these substances have low melting and boiling points. Unlike ionic bonds, they do not conduct electricity.(Different Substances and Their Properties)

Ionic bonds occur between a metal and a non-metal. This is because, all atoms want to fulfill something called the octet rule. The octet rule is a rule that states that all atoms form bonds in a way that fills their outrmost shell (in most cases that has 8 electrons). In an ionic bond, atoms tend to gain and lose electrons, which either gives them a positive or negative charge, which can also be referred to as an ion.
