Step 3: Develop your solution. In your solution provide evidence to support your solution, explain at least three environmental impacts of your solution, include constraints like cost, safety, and reliability, then describe the strengths and weaknesses of those constraints rest of the questions shown down below in images

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.
