Chemical Bonds and Metallic Bonding
You'll encounter three main types of chemical bonds depending on what elements are combining. Metallic bonding occurs between metals, ionic bonding happens between metals and non-metals, and covalent bonding forms between non-metals.
Metallic bonding creates a unique structure where positive metal ions arrange in regular rows. The magic happens because electrons can move freely throughout this structure, creating strong electrostatic forces that hold everything together. This is exactly why metals conduct electricity so well - those mobile electrons carry the charge!
Alloys are simply mixtures of different metals that are tougher than pure metals. When you mix metals with different-sized atoms, the layers become distorted, making it harder for them to slide past each other. This distortion is what makes alloys so much more durable than pure metals.
Quick Tip: Remember the bonding rules by thinking about the periodic table - metals on the left love to give away electrons, whilst non-metals on the right want to grab them!
