If you have 25 Hydrogen-1s and 75 Hydrogen-2s, how many total hydrogens do you have? (yes, it’s THAT simple! Don’t complicate the addition.) This is such a simple question but the answer is 100 right, the answer would not be 175?

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.
