A mollusk fossil is found in rock layer 3 and a leaf imprint is found in rock layer 1. Which of the following statements is
true?

The leaf imprint is older than the mollusk fossil

The leaf imprint is younger than the mollusk fossil

The leaf imprint is the same age as the mollusk fossil

it's filtration, but this is an assumption so my apologies if i got this

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.
