Oxygen, hydrogen, halogens
Very probable this element is oxygen.
The chemistry of polonium is not known in details but I suppose that this element is oxygen.

Polonium doesn't contain another element.
Polonium doesn't contain another element.
Natural polonium exist probable as a compound (as PoPb) but this hypothesis was not surely confirmed up today.
this is a guess but beryllium?
no, it is most commonly found as a compound
Sodium
Polonium is not commonly found in nature, as it is a highly radioactive element with a short half-life. It can be found in small trace amounts in uranium ores, but is mostly produced artificially in nuclear reactors. It is not typically found in consumer products or the environment.
hydrogen is most commonly found as a part of water with oxygen.
