What is Metallic Bonding?
Think of metals as having a completely different bonding system compared to ionic or covalent compounds. Metallic bonding creates a structure where positive metal ions sit in a lattice surrounded by a sea of delocalised electrons.
Here's what happens: when metal atoms come together, their outer electrons break free and can move throughout the entire structure. These delocalised electrons aren't attached to any specific atom - they're shared by all the metal ions.
The whole structure is held together by electrostatic forces of attraction between the positive metal ions and the negative sea of electrons. This creates what we call a giant metallic structure because the bonding extends throughout the entire piece of metal.
💡 Key Point: The number of delocalised electrons depends on how many electrons each metal atom loses - magnesium loses 2 electrons per atom, so it contributes more to the electron sea than sodium (which loses just 1).

Why Metals Conduct and Have High Density
Metals are fantastic conductors of electricity because those delocalised electrons can move freely through the lattice to carry electrical current. When you connect a metal to a battery, electrons flow in one end and out the other without any problem.
Heat conduction works similarly - energy spreads quickly through both the metal ions and the mobile electrons throughout the structure. That's why metal spoons get hot so quickly when you leave them in your tea!
Metals typically have high density because the metal ions pack tightly together in their lattice structure. Even though diagrams show them spaced apart for clarity, they're actually crammed close together with the electron sea filling all the gaps.
💡 Remember: It's the mobile delocalised electrons that make metals such good conductors - something ionic and covalent compounds typically can't do.

What Makes Metallic Bonds Strong?
The strength of metallic bonding depends on two main factors that you need to remember for exams. First, the charge on each metal ion - higher charges mean more delocalised electrons and stronger electrostatic attraction. Second, the size of the ion - smaller ions keep the electrons closer to the positive nucleus, creating stronger bonds.
This explains why metals like aluminium have stronger metallic bonding than something like sodium . You can predict properties just by thinking about these two factors.
Malleability and ductility happen because metal ions can slide over each other when force is applied. Unlike ionic compounds that shatter, the electron sea continues to hold everything together even after the structure has been deformed.
💡 Exam Tip: Always mention both charge and size when explaining metallic bond strength - you'll get marks for both factors.

Physical Properties of Metals
Metals generally have high melting and boiling points because of their giant structures. Those strong electrostatic forces between metal ions and the delocalised electron sea require loads of energy to break apart, making it difficult to separate the ions.
Solubility is straightforward - metals are insoluble in water and most solvents because the metallic bonding is simply too strong to be disrupted. The only exception is when metals dissolve in other liquid metals, forming alloys.
Understanding these properties helps you predict how metals will behave in different situations. Whether it's explaining why copper wires conduct electricity or why gold can be hammered into thin sheets, it all comes back to that sea of delocalised electrons.
💡 Quick Check: Can you explain why metals don't shatter like ionic compounds when hit with a hammer? It's all about those layers sliding while staying bonded!
