Question

Metallic solids are solids made entirely of:
a.) One metallic element
b.) Multiple metallic elements
c.) Ionic bonds
d.) Covalent bonds

Answer 1

Hint: To answer this question you should know that metallic bonding arises from the electrostatic attractive force between conduction electrons and positively charged metal ions. Now you may have got some idea about the metallic solids.

Complete step by step answer:

Metallic crystals contain atoms with the same charge surrounded by a sea of electrons. Since these electrons are free to move within the crystal structure, metals are good conductors of electricity and heat.
In addition, it is this freedom of the electrons to move that allows metals to be both malleable and ductile: Since the bonding is the same in all directions, the atoms can slide past each other without breaking.
Most metals have very few valence electrons in their outermost shells; metals also possess vacant electron orbitals just below their highest energy levels which results in some overlapping of vacant shells. Because of this, the electrons of metals tend to roam freely between the energy levels and do not belong totally to any one atom.
Hence, we can say that metallic solids are solids composed of metal atoms that are held together by metallic bonds. These bonds are like huge molecular orbitals that span across the whole solid. This means the electrons in metallic solids are delocalized. They are not just held between a couple of atoms in a sigma bond.

Therefore, the correct answer to this question is option B.

Note: Let’s also discuss ionic bonding.
Ionic bonding occurs when elements either gain or lose valence electrons in order to become more stable.
Elements such as sodium will usually lose an electron, resulting in a positively charged atom, while elements like chlorine usually gain an electron which allows the atom to become negatively charged.
These atoms readily form a compound due to the strong electrical attraction.
