15 points which best explains how radiation is in the plastics industry? it makes plastics easier to shape. it adds a protective layer to plastic. it decreases the melting point of plastic. it improves the strength and durability of plastic.

Just took the test

It makes plastic easier to shape

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
