What is precipitation? the sweat from our bodies on hot days
the gas that we use in furnaces and ovens
any form of water that falls from the sky
warm rain, but not cold snow or sleet

Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain. Precipitation isn't always in the form of warm liquid. It also includes snow ,sleet ,hail ,and such.

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.
