Ben was asked to do an experiment for his science fair project. He wanted to know if salt water came to a boil faster than distilled water. His hypothesis was
that the salt water would boil faster than distilled water. He conducted an
experiment under controlled conditions. Distilled water came to a boil faster in all
of his experiments. What should he do? *

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.
