Barometric pressure can be measured in inches (a meteorologist might say that the barometric pressure is 29.92 inches Hg), but in the metric system we would say that the barometric pressure at sea level is: Find and type in at least 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.
