2. Develop a series of sketches showing how an electron of an atom can give off light. Your first sketch should have the electron in the ground state. The next sketch should show the electron excited when you apply energy to the atom and the third sketch should show how light is emitted when the electron falls to a lower energy state.

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.
