Metals are $"malleable"$, capable of being hammered into a sheet, and $"ductile"$, capable of being drawn out into a wire. This workability makes metals the premier materials for making tools. These properties are believed to result from $"metallic bonding"$, in which the are delocalized across the metallic lattice.
Actual chemical , as opposed to metals and their alloys, tend not to share these properties.
By definition, ALL metals are malleable and ductile, and so this property is not restricted to the Group 2 metals. (Ductility is the ability of a metal to be drawn...
Metals are excellent conductors because the atoms in a metal form a matrix through which their outer electrons can move freely. Instead of orbiting their respective metal atoms, they form...
Because the delocalised electrons are free to move. Metallic bonds are formed by the electrostatic attraction between the positively charged metal ions, which form regular layers, and the negatively charged...
$"Metallic bonding"$ results from the close packing of metal atoms, such that the atoms contribute a few of their to the overall lattice. These are delocalized, and not associated with...
In a metallic bond, each metal atom is conceived to donate one or two or more to the bulk lattice. The result is commonly described as $"metallic bonding"$, $"positive ions...
..........and, therefore, cannot carry a current. In a melt (for which typical ionic solids must be raised to very high temperatures), or solvated by polar molecules in a solution (typically...
because covalent bonds are formed by sharing of electrons..they don't have a free electron that is required for electricity transfer(electricity is the flow of free electrons!) thus they re bad...

Ductility is the ability to be drawn out into a wire. Malleability is the ability to be hammered out into a sheet. Copper is not a particularly hard metal, and...
