Because it tends to give up electrons easily.
Metals contain metalic bonds which have free electrons unlike ionic or covalent bonds. As those electrons could flow freely along the metal structure, metals can conduct electricity.
Plastics are filled with covalent bonds ... which block the flow of electrons. Whereas metals share their electrons, thus facilitating their flow.
Metals have a characteristic silvery, shiny appearance, they are electrically conductive, flexible (except for mercury which is liquid), and they engage in chemical reactions in which they are electron donors, forming positive ions. Non-metals are less shiny, generally not good electrical conductors, not as flexible, and they engage in chemical reactions in which they receive electrons, forming negative ions. Some non-metals such as carbon can either give or receive electrons, but even when they give electrons they do not do so as readily as metals do.
It would be a good conductor. With bonds that explain gold's properties
It varies on which metalloid you are talking about but in general they have low melting points
they have a great tendency to lose electrons
they have a great tendency to lose electrons
Covalent bonding does not necessarily require that the two atoms be of the there is good overlap between the atomic orbitals of participating atoms.

Ionic bonds occur between a metal and non metal; electrons are removed or added between elements; and are good conductors of heat and electricity in water. Covalent bonds occur between two non metals; electrons are shared; and not good condctors
Metallic aluminum does not form chemical bonds, in all metals the outer electrons escape forming an "electron gas" that fills the bulk of the metal. This is why metals are both good electrical conductors and thermal conductors.
if they have free-flowing ions. Liquids, and metals often have these ions. BUT NOT WHEN THERE ARE COVALENT BONDS. Only ionic in liquid form. sorry this answer sucks.
The answer is (d). In covalent and ionic bonds the electrons are tightly bound. shiny and hard are qualities most (but not all) metals have but are also shared by non-conducting solids
Some chemical properties of metals are that they have good electrical and thermal conductivity. Metal also form positive ions or cations and ionic bonds. When exposed to air and moisture, many metals tend to corrode.
Ferrous metals react with oxygen in the atmosphere, forming rust.
Non-polar, single and covalent BondA bond between two non-metals is generally going to be a covalent bond due to the affinity to electrons and the need to "pick them up." Molecular hydrogen is a good example and the hydrogens are indeed bonded by a covalent bond, sharing electrons to complete a full valence shell. In the category of covalent bonds, there are polar and non-polar covalent bonds. In some covalent bonds, electrons are shared unequally, resulting in the partial charge of one atom and the opposite charge of the other atom(s). This occurs when one atom in the compound has a higher electronegativity, or affinity to electrons.But because both atoms in the molecule H2 have the same electronegativity (as atoms of the same element), electrons are shared more or less equally, resulting in a non-polar covalent bond.
