Metallic bonding - Wikipedia

2019-4-23 · Metallic bonding is a type of chemical bonding that rises from the electrostatic attractive force between conduction electrons (in the form of an electron cloud of delocalized electrons) and positively charged metal ions. It may be described as the sharing of free electrons among a structure of positively charged ions ().Metallic bonding accounts for many physical properties of metals, such as

What type of bond does calcium and chlorine have? - …

Whenever calcium, or just about any metal for that matter, forms a bond with another element, be it a metal or non-metal, it will form an ionic bond; this is due in part to the low electronegativity of Calcium, as it will strip the other atom of its excess electron(s) rather than experience a mutual exchange of electrons.
