Elements + Bonding
In a solid metal, the atoms are arranged neatly in a simple pattern known as a lattice.
W - A LATTICE is a regular repeating pattern.
In metals the outer energy level of each atom overlaps with it’s neighbours. The ‘positive core’ of an atom is the nucleus and the inner electron clouds. This means the outermost electrons become ‘delocalised’, not fixed to any particular atom, and can move throughout the lattice. This explains why metal s can conduct electricity and heat. The metallic bond is the electrostatic attraction between the positive and…
