I need an answer based on its atomic and molecular structure (molecular structure is proffered). Also is plastic a giant molecular, simple molecular or lattice substance? thanksss:) x
Plastics are preferred because they are lightweight, rigid, durable, nonporous, nonconductive, cheap, and readily available. Plastics can be molded to any shape, and they are excellent protection for the delicate electronic components within. Contrast with metal, which conducts electricity, is malleable rather than rigid, and is usually more expensive than plastic. All of the physical properties of plastic that make it an ideal material for use with making phones derive from its molecular structure. Plastics are polymers, long repeating carbon chains, so they are giant molecules, although filler materials are often used that could change this significantly. The monomers can be changed chemically to alter the properties of the finished plastic, leading to an almost limitless variety of plastics that can be used not only for mobile phones, but computers, bags, cups, chairs... nearly anything.
