Metals are elements that lose electrons easily that are lustrous reflective malleable can be molded into other shapes and are good conductors of heat and electricity. This is why metals are good conductors of electricity. Giant implies that large but variable numbers of atoms are involved - depending on the size of the bit of metal.

Updated on September 22 2019 The definition of metal. What types of bonds are shown in the lewis structure of BCl3. Metals account for about two thirds of all the elements and about 24 of the mass of the planet.
Cubic close packing is defined as a crystalline structure in which planes of closely packed atoms or ions are stacked as a series of three alternating layers of different relative orientations. This is because the rows of atoms in the metal dont line-up. A tapered pin used to align holes in steel members to be connected.
In that crystal metal atoms occupy the eight corners of a cube along with one atom in the very center. Crystalline materials include metals ceramics and parts of some polymers opposite of noncrystallineamorphous crystal structure. Metals are otherwise defined according to their position on the Periodic Table.
