and density to the lowest air pressure and density.
Exosphere, Thermosphere, Mesosphere, Stratosphere, Troposphere
Oxygen, nitrogen, argon, carbon dioxide
Troposphere, stratosphere, ozone, thermosphere, outer space
Troposphere, stratosphere, mesosphere, thermosphere, exosphere

well in order to answer this question you have to provide more information < 3

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.
