Brief Explanations:

In a metal, the out - ermost electrons of metal atoms are not bound to a single atom. They are free - roaming, delocalised, do not belong to any particular metal atom, and together form a "sea of electrons". This is due to the metallic bonding where metal cations are surrounded by a cloud of these mobile electrons.

A. free - roaming, B. delocalised, C. they don't belong to any particular metal atom, D. "sea of electrons"
