Question

In a sample of which element would you expect to find a sea of electrons surrounding nuclei?

N

He

Na

Ag

Answer 1

Ag

Step-by-step explanation:

• Metals are elements in the periodic table that react by losing electron(s) to attain a stable configuration.
• Metals are characterized by being good conductors of electricity and heat due to the presence of delocalized electrons.
• Metals also have high boiling and melting points due to the presence of a strong metallic bond.
• Metallic bond in metals occurs due to the attraction between the positively charged nuclei and the negatively charged sea of electrons surrounding the nuclei.
• In this case, silver is the best conductor of both heat and electricity due to presence of delocalized electrons.

Answer 2

Ag (Silver)

Step-by-step explanation:

Silver (Ag) is the element that has the best conduction of heat and electricity, being considered as a noble metal because it is highly resistant to corrosion.

Silver has an atomic number of 47, which indicates its number of electrons and protons (as atoms are electrically neutral, the number of protons and electrons is equal) in their nuclear orbitals.

Silver has a relatively high atomic number compared to atoms like nitrogen (N), with atomic number 7, helium (He), a noble gas with atomic number 2, or sodium (Na) with atomic number 11.
