Question
Lead is malleable, so it can be pounded into flat sheets without breaking. How does the bonding within lead help to explain this property? Metallic bonds involve valence electrons that are removed from one atom and given to another, so the pounding helps the electrons move. Covalent bonds involve valence electrons that are shared between two metal atoms so the bonds are strong enough to resist the pounding Metallic bonds involve many valence electrons shared by many atoms, so the bonds can move around as the metal is pounded Covalent bonds involve valence electrons that are removed from one atom and given to another, so the pounding helps the electrons move.

Metallic bonds involve many valence electrons shared by many atoms, so the bonds can move around as the metal is pounded.
Explicação
## Step 1The problem is asking us to identify the type of bonding within lead that allows it to be malleable. Malleability is a property of metals, which means that metals can be hammered or rolled into thin sheets without breaking. This property is due to the nature of metallic bonding.## Step 2Metallic bonding involves the sharing of many valence electrons among many atoms. This creates a 'ea' of delocalized electrons that are not confined to a single atom but can move freely throughout the structure of the metal. This 'ea' of electrons allows the atoms in the metal to slide past each other when force is applied, such as when the metal is pounded.## Step 3Covalent bonding, on the other hand, involves the sharing of valence electrons between two non-metal atoms. This type of bonding does not allow for the free movement of electrons and does not contribute to the malleability of metals.
