which two constitues are present in ionic compound?
Answers
Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. (A cation is a positively charged ion; an anion is a negatively charged ion.)
Hope it will helps ✌
Explanation:
Malleability and Ductility
PrintPrint
Malleability and ductility are related. A malleable material is one in which a thin sheet can be easily formed by hammering or rolling. In other words, the material has the ability to deform under compressive stress.
Malleability: Metal hammered into thin sheets, shows hammer hitting gold to make thin circle
A malleable material is one in which a thin sheet can be easily formed by hammering. Gold is the most malleable metal.

In contrast, ductility is the ability of a solid material to deform under tensile stress. Practically, a ductile material is a material that can easily be stretched into a wire when pulled as shown in the figure below. Recall pulling is applying tensile stress.

If we pull on a rod of material, some of the possible profiles of the rods at fracture are shown in the figure below.
Breaking profiles: A) Snap w/ jagged edges. B) some contour and pulling then snap, C)pull all the way into smooth contours and points

Profile (a) is an example of the material that fractures with no plastic deformation, i.e., it is a brittle material. Profile (b) is an example of a material that fractures after very little plastic deformation. These two profiles would be classified as having low ductility. Profile (c) in contrast is a material that plastically deforms before fracture. This material has high ductility. The stress-strain curves for the brittle, profile
