You are working in a lab on your magnetic levitation experiment. You are standing directly in front of two magnets. Another scientist near you has a malfunction with their equipment and beta radiation is emitted directly at you, passing through the magnets first. You are wearing a lab coat and goggles. Are you safe?

lol idk man i guess u gotta ask bill nye the science guy

it is b that is the answer.

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.
