In the readings, a claim is made that in a chemical reaction, matter is not created or destroyed. Create an argument to support this claim. Give reasons and evidence from the texts. Also tell
what you may already know about chemical reactions.

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.
