In a sample of which of these elements would you expect to find a sea of electrons surrounding nuclei? . a) ar. b) au. c) o. d) n.

B) Au

Explanation:

Electron sea model:-

It assumes that the electron of the metal atoms tends to flow between the nuclei of the metal easily.  

It is model which shows the metallic bonding in which the cations of the metal are at the fixed places and the negatively charged electrons move freely within them.  

Since, out of the given options, Au is the only metal and it only has metallic bond which has a sea of electrons. Thus, answer is:- B) Au

a. they are both space stations
