1. Define atom and elements. 2. Define Malleability and Ductility. 3. Explain Sonorous and Lustrous
Answers
Answer:
Atoms are the smallest component in Basic Chemistry Which are building units of a Chemical substance. Elements are those which consists of a Single type of atoms.
Malleability is a beating of metal into thin sheets; pliability is a making metal into thin wire.Malleability is a property that portrays the capacity of a material to extend thin when tractable pressure is connected.Flexibility is the capacity to curve or shape a material utilizing compressive power.A few materials are both flexible and pliable.
Therefore they are lustrous. The property by virtue of which metal can be beaten into sheets is called malleability. We use aluminium foil to pack food. The property by which metals can be drawn into wires is called ductility

Explanation:
A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just one proton and one electron
Malleability is the ability of a material to deform under stess (compressive stress). If a material is malleable then it can be converted into thin sheets by hammering or rolling. Ductility of a material is the ability to stretch under stress (tensile stress). ... Generally many metals have high malleability and ductility.
Sonority is the property of a substance to produce sound when collide together. Metals are sonorous and produce sound when struck together in solid state. Electron bonding in metals is highly delocalized, due to their very low electronegativity.
Lustrous is the property of a substance to produce a shine when light falls on it.Example are gold,silver,etc.
