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.)
Ions
solids
They vibrate
Protons, Neutrons and Electrons.
Electrons.
Changes in particles, such as their movement or arrangement, can lead to energy transfers through processes such as conduction, convection, and radiation. For example, in conduction, heat energy is transferred through direct contact between particles in a material. In convection, energy is transferred through the movement of fluid particles, such as air or water. Radiation involves the transfer of energy through electromagnetic waves, without the need for particles to directly interact.
YES. THEY EAT ORGANIC PARTICALS
Sometimes, if they are a crystalline solid.
gas particals
It breaks down food particals
Liquid gAs solid
This is called homogeneous.
