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 .

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
