Most are closely bound to atomic nuclei, in orbits. However some are delocalised, and are free to move through the metal. It is this sea of electrons that give metals their well know charaterisics: they are good conductors of electricity and heat, and have a shiny surface.
They transfer from the metal to the non-metal. This forms positive and negative ions, which then attract each other to form an ionic bond.
nickel has 28 electrons and is in the metal family
In metallic bonds, electrons are delocalized and free to move throughout the structure of the metal. They are not bound to a specific atom and instead contribute to the overall bonding and properties of the metal.
Electrons exist as pairs. Although, electrons hate each other, and only go as pairs as a last resort.
Cu(2-) does not exist, because Cu does not gain electrons at all being a metal. When it gives off two electrons Cu(2+) ions are formed.
Calcium is a metal that has two valence electrons.
Yes, metallic bonding does exist in iron. Iron is a metal and its atoms are held together by metallic bonds, which involve the sharing of electrons among a sea of delocalized electrons. This accounts for its characteristic properties like malleability, ductility, and high electrical conductivity.
Free electrons in a metal are called conduction electrons. These are loosely bound to the metal lattice and are able to move freely throughout the material, allowing metals to conduct electricity efficiently.
In a chemical reaction between a metal and a non-metal, electrons are typically transferred from the metal to the non-metal. The metal loses electrons to form cations, while the non-metal gains electrons to form anions. This transfer of electrons results in the formation of an ionic bond between the two elements.
Zinc has 30 electrons.

Metal ions do not share electrons with one another. Metal ions have a positive charge.
