Different types of bonding play a big role in how stable crystal structures are. This is what makes them special and gives them different properties. Let’s break it down:

1. Ionic Bonding:

   • This happens when there are strong attractions between positive and negative ions.
   • Because of these strong forces, ionic compounds have high melting and boiling points.

2. Metallic Bonding:

   • In metals, electrons are not stuck to one atom. Instead, they move freely around metal atoms, creating what we call a 'sea of electrons.'
   • This makes metals good at conducting electricity and allows them to be bent and shaped without breaking.

In simple terms, ionic solids are hard and can break easily, while metallic structures are more flexible and can carry electricity well. The kind of bonding in these materials really affects how they react when there is stress and how stable they are overall.
