Question

a metal is a answer consisting of closely - packed atoms. in most cases, the outermost electron shell of each of the metal atoms overlaps with a large number of neighboring atoms. as a consequence, the answer electrons continually move from one atom to another and are answer associated with any specific pair of atoms. in short, the valence electrons in metals, unlike those in covalently - bonded substances, are answer, capable of wandering relatively freely throughout the entire crystal. the atoms that the electrons leave behind become answer ions. it is this free movement of electrons that allows metals to carry an answer current.
electrical solid valence nonlocalized not positive

Explanation:

Metals are solids with closely - packed atoms. The outermost (valence) electrons can move freely among atoms and are non - localized, not associated with specific atom pairs. When electrons leave, the remaining atoms become positive ions. This free movement enables electrical current conduction.

Answer:

1. solid
2. valence
3. not
4. nonlocalized
5. positive
6. electrical
