Question

This is the type of attraction that holds elements like nickel, sodium and gold together. For these elements, stationary, positive-charge ions are surrounded by a sea of shared, freely-moving electrons.

Answer 1

metallic bonding

Step-by-step explanation:

In metallic bonding positive charged metal cations are embedded in a sea of valence electrons. The electrons are not tightly held by a single metal cation. The freely moving electrons endow a metal with all its metallic properties such as ductility, malleability and ability to conduct electricity.

Answer 2

The answer is metallic bonding as this bond is the one responsible of having to provide attraction in the electrons and atoms that could lead of having substance to be made as a glue in order to provide definite structure and it explains the description above.
