Not all the elements occur naturally; some elements are man-made.
They are naturally occurring.
Most of the 92 naturally occurring elements can be classified as either metals or non-metals. Metalloids, also known as semi-metals, are a smaller group of elements that have properties of both metals and non-metals.
krypton and barium are both naturally occurring non-radioactive elements. krypton can be extracted from air by fractional liquefaction. barium ore can be mined and barium extracted.
Both. Viruses are naturally occurring organisms that have been around "forever". They have the ability to mutate or change themselves into new shapes and types sometimes using genetic material from more than one kind of virus, which would make them naturally occurring hybrids. They were not man-made.
A rock is mineral like a crystal .Also they both are solids A mineral, by definition, is any naturally occurring, inorganic substance, often additionally characterized by an exact crystal structure. Its chemical structure can be exact, or can vary within limits. Elements that occur naturally are also considered minerals like rocks.
The materials used to manufacture ceramics are naturally occurring. These naturally occurring materials include silica, sand, quartz, flint, silicates, and aluminosilicates.
Both. Zinc can be found in nature and also can be manmade.

You make steel by combining iron and coal. Usually a 8:1 or 9:2 ratio Both can rust and are good conductors of electricity
Yes, both are common in well water
krypton and barium are both naturally occurring non-radioactive elements. krypton can be extracted from air by fractional liquefaction. barium ore can be mined and barium extracted.
Both types are part of the rock cycle. Both rocks contain various minerals. Both are solid. Both are naturally occurring. Both are found in the crust.

they both use turbines to produce electricity

Of the 92 naturally occurring elements, living things are composed of only about 25, and SIX of those make up practically all of the weight of most living things.
