Consider the following statements regarding metallic bonding: 1. The metallic sharing changes with time and the bonding electrons resonate between different atoms. 2. The metallic state can be visualized as an array of positive ions, with a common pool of electrons to which all the metal atoms have contributed their outer electrons. 3. These electrons have freedom to move anywhere within the crystal and act like an all-pervasive, mobile glue holding the ion cores together. Which of the above statements are correct?
