Mass and weight are related via the equation W=mg on Earth. Mass is how much matter an object has and weight is the measure mass under a gravitational field (on Earth g =9.80m/s2). Suppose you go to an unknown planet-X where the gravitational field of the planet is g’= 23.15m/s2. Will a metal have a higher, lower, or the same density on planet-X when compared to Earth. Assume the volume of the metal doesn’t change

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.
