Francium, Uranium, Thorium, Plutonium, Radium, Neptunium,
Some examples are deuterium and tritium which are radioactive isotopes of hydrogen.
No, some radioactive materials are not solids. Most radioactive materials are solids (uranium, plutonium, isotopes of many other materials) Some radioactive materials are gases (Radon) or isotopes of gases (Tritium, carbon fourteen, etc.)

Some examples are deuterium and tritium which are radioactive isotopes of hydrogen.
Fluids are materials that have no fixed shape and are free to flow, such as gases. Gases are also fluids.Here are some examples of fluids:WaterBloodAirGasHydrogenHeliumOxygen etc...
examples of raw materials are Diamond, Suger and Aluminum.
the examples are fabric cloth,glass
Electrons. Electricity is composed of free electrons and some radioactive decays emit electrons (beta particles)
Radioactivity refers to the emission of ionizing particles which results from the spontaneous disintegration of atomic nuclei. Some examples of radioactive elements are uranium and plutonium.
Some examples of basic materials include wood, steel, concrete, plastic, and glass. These materials are commonly used in construction, manufacturing, and everyday household items.
The same element can have different half-lives, for different isotopes. You can find a list at the Wikipedia article "List of radioactive isotopes by half-life". This list is NOT complete; a complete list would have about 3000 nuclides (that is, isotopes).
An atom whose nucleus decays over time is called radioactive. Some examples of radioactive substances are uranium, plutonium, and einsteinium.
