The group of elements with the most stable configuration
Typically, atoms gain or lose electrons to achieve
a stable electron configuration.
In an electron dot diagram, the symbol for an element is used to represent
the nucleus and valence electrons.
The formation of an ionic bond involves the

A metallic bond
The attraction between a metal cation and a shared pool of electrons
Why can many metals can be drawn into thin wires?

In lithium iodide, LiI, which element is the anion and which is the cation
lithium (cation), iodine (anion)
Are covalent bonds more likely to be found in compounds containing both metals and nonmetals or compounds containing only nonmetals?
Metals are good conductors of electric current because
metals contain a shared pool of electrons that are free to move.
