Pitchblende uranium ore UO2
Ununhexium is a radioactive chemical element.

No element contains any kind of bond except a metallic one. Ionic bonds can occur only between at least two different elements.
Transition elements are the major group of elements with this property.
Elements are matter made of one kind of atom.elements
These are the radioactive elements. See this link.
Radium is a white metal that does not occur in a free state; it must be refined from pitchblende and occurs naturally only as a disintegration product in the radioactive decay of thorium, uranium, or actinium.

For example very rare radioactive chemical elements.
h2o and sodium chloride. (Salt and water) Almost all elements are found in sea water. Some elements are man made and do not occur naturally. Salt is the most abundant but if you had the gold from a square mile of sea water, you would be one rich son of a gun.

Homogeneous refers to parts and elements that are the same kind. It can also occur in nature and has common properties, like soil.
