You have four questions above, I will give 4 quick answers.

Metals are valued for their malleability and ductility, which are explained by metallic bonding. Malleability is the ability of a material to be beaten out into a sheet, while ductility is the ability to be drawn out into a wire. Bond polarities refer to the covalent bond. In a polar covalent bond one of the participating elements has polarized electron density to its side of the bond, and the element has acquired a partial negative charge, whereas its partner acquires a corresponding positive charge. The #O-H# bond in water is a classic example of a polar covalent bond; the more electronegative oxygen has acquired a partial negative charge. These concepts allow for predictions about the nature of the bond, its strength, and potentially its reactivity. You will have to look for the applications yourself. There are more comprehensive and in-depth explanations of these topics available on Socratic; you'll need to search for them with Google.

undefined (i) Malleability is the property that allows a material to be shaped or deformed without breaking through compression, like hammering or rolling; (ii) Ductility is the property that allows a material to undergo significant deformation without rupture or breaking, usually through stretching or pulling, to form a thin wire or filament; (iii) Metallic bonding is a type of chemical bonding between metal atoms, where the outermost electrons are delocalized and free to move throughout the structure, creating a "sea of electrons" that holds the positively charged metal ions together; (iv) Bond polarity is the property that results in an uneven distribution of electrons between atoms in a chemical bond, giving one atom a partial positive charge and a partial negative charge on the other.
