(C) Assertion is correct but Reason is incorrect
(D) Both Assertion and Reason are incorrect

Answer 1

Metals are elements that readily produce positive ions (cations) and have metallic connections in chemistry. A metal is a substance that has a glossy look when freshly produced, polished, or shattered, and conducts electricity and heat reasonably effectively. Metals are usually ductile or malleable.

Complete answer:
Metallic bonding is a type of chemical bonding that results from the electrostatic attraction between positively charged metal ions and conduction electrons (in the form of an electron cloud of delocalized electrons). It may be characterised as the sharing of free electrons among positively charged ions in a structure (cations). Many physical characteristics of metals, such as strength, ductility, thermal and electrical resistivity and conductivity, opacity, and brilliance, are determined by metallic bonding. Even as a pure material, metallic bonding isn't the only sort of chemical bonding a metal may have.
The bonds in a metal are metallic, i.e. non-directional. There are no bonds that are exclusive to a certain location. As a result, metal ions may readily glide over one another (i.e. can move from one lattice to another). Metals are malleable because they may be formed into thin sheets without destroying their metallic links.
Electrons are shared by many atoms in a metallic connection. As a result, they're non-directional.
As a result, both assertion and reason are right, though reason is not the proper explanation for assertion. Option B is correct.

Note:
The capacity of a substance to distort under pressure is known as malleability (compressive stress). If a material is malleable, it can be hammered or rolled into thin sheets. Metal leaf may be made from malleable materials. Gold leaf is a well-known form of metal leaf. Many metals with a high malleability have a high ductility as well. Some don't, such as lead, which has a low ductility but a high malleability.
