Question

its time for the unit exam. this is your opportunity to show how much you have gained if you dont feel ready, you may want to stop and clarify anything you do not understand any notes you have taken and review the key terms. good luck! note: to answer some of the questions, it may help to reference a periodic table. what do the blue dots represent? the distinct and rigid bond between the different metal atoms the sea of electrons being freely shared between the positive nuclei of the metal atoms the positive nuclei of the metal atoms held in place by the attractive forces with the sea of electrons the unshared pairs of electrons of the metal atoms involved in the metallic bond

Explanation:

In metallic bonding, metals have a "sea of electrons" that are delocalized (freely shared) among the positive nuclei (cations) of the metal atoms. The green circles with a plus sign represent the positive nuclei of metal atoms. The blue dots represent electrons. Metallic bonding is not about distinct rigid bonds (as in covalent or ionic in a strict sense for metals in this context - metals have a more mobile electron situation), the positive nuclei are the green +, and unshared pairs are not relevant here as it's about delocalized electrons in the sea model.

Answer:

the sea of electrons being freely shared between the positive nuclei of the metal atoms
