Question

Metallic bonds do not play a role in
a)Brass
b)copper
c)Germanium
d)zinc​

Answer 1

(c) Germanium.

• Germanium is a type of metalloid (metal and non metal nature).
• As a result, it does not form metallic bonds like pure metals such as copper and zinc.
• A metalloid is a chemical element with properties that fall somewhere between metals and nonmetals.
• The term "metallic bond" refers to the sharing of a sea of valence electrons by a group of positively charged metal ions.
• In general, metalloids form covalent bonds with nonmetals.
• Metals lose their electrons and can only form ionic bonds.
• Metalloids and nonmetals can form ionic bonds by either losing or gaining electrons, in addition to covalent bonds.

Answer 2

Metallic bonds do not play a role in Brass.

Option a) Brass.

• The forces (metallic bonds) which hold the metal atoms together are known as metallic bonds.
• Metallic bonds are present only in metals.
• They hold or keep a metal i.e., close packing.
• These bonds come from the electrostatic attraction between the cations and the electrons of the metal atoms.
• We can determine the metallic bonds using physical properties like ductility, malleability, and others.
• Since Brass is an alloy it doesn't have the metallic bonds
• Copper is metal so hence it might have metallic bonds, unlike brass and others.
• Similarly, Germanium and Zinc also have metallic bonds. Because they are metals.
• Hence, from the above discussion we came to know that the metallic bonds do not play a role in Brass alloy.
