Is radioactive radiation an element compound homogeneous mixture or heterogeneous mixture?

Answer 1

Hydrogen is an element.

Answer 2

It could be either. If you have, say, some radioactive caesium (an element) and you chlorinate it, you'll have the compound caesium chloride, and it will be radioactive. If you take some radioactive powdered cobalt-60 and mix it with sugar, it's a mixture (and a nasty one). In general, it is an atom or, said differently, an atom of an element, that is radioactive. The only question is whether that atom of the given element is in a pure (or elemental) form, or whether it is in a chemical compound with something, or whether it is mixed in with something else to form a mixture. Something that is radioactive is composed of (either all or in part) a radioactive nuclide (one or more) of a given element or elements that are in there.

Answer 3

Radioactive radiation is not a physical substance, so it cannot be classified as an element, compound, homogeneous mixture, or heterogeneous mixture. Instead, it refers to the emission of energy in the form of particles or waves from certain unstable atoms.

Answer 4

Radioactive radiation is not a material

Answer 5

Radium is an element.

Answer 6

Hydrogen is an element.
