WebA giant metallic structure Metallic bonds are very strong so in general metals have high melting points and are strong and hard. The layers of metal ions are able to slide across … WebGraphite has its carbon atoms arranged into layers with relatively strong bonds within the layer and very weak bonds between the layers. Thus graphite cleaves readily between the layers and the layers slide easily over one another giving graphite its lubricating quality. Mineral fracture surfaces may be rough, uneven, or show a conchoidal fracture.

WebIn metallic bonding the outer shells of adjacent atoms overlap, and the outer shell electrons are free to move through the lattice. The metal consists of metal cations and a balancing number of these ‘free’ electrons.
