which property of metals is explained by the "sea of electrons" within metallic bonding?
a. malleability
b. all of the above
c. electrical conductivity
d. thermal conductivity

B. All of the Above

Explanation:

Sea of electrons -

This model of the metallic bonding helps in explaining the properties like ,  malleability , ductility ,high electrical conductivity ,  luster ,high thermal conductivity of the metals in solid state .

The metallic bonding is between metal atoms and the ionic bond links a metal and a non - metal together ,

In case of metallic bonding , bulk of metal atoms are joined .

hence from the question , all the given properties are correct .

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
