Question

a sea of mobile electrons is characteristic of which bond? 1. metallic 2. ionic 3. covalent

Explanation:

In metallic bonding, metal atoms release their outer - shell electrons, creating a 'sea' of delocalized or mobile electrons that surround the positively - charged metal ions. Ionic bonds involve the transfer of electrons between a metal and a non - metal to form ions, and covalent bonds involve the sharing of electrons between non - metals.
