A mass of unstable atoms is known as a radioactive material. These atoms undergo spontaneous decay, emitting radiation in the form of particles or electromagnetic waves in order to become more stable. Examples of radioactive materials include uranium-235 and carbon-14.

What are mass of unstable atoms?

The mass of unstable atoms can vary widely depending on the specific isotope and the decay process involved. Unstable atoms typically have a higher mass compared to stable atoms due to the presence of excess energy or additional subatomic particles. When unstable atoms undergo radioactive decay, they can transform into more stable elements by emitting particles and energy.


Is fusion nuclear decay or nuclear synthesis?

Fusion is nuclear synthesis, combining atoms of lesser mass into atoms of greater mass. Decay is reducing the mass of larger (unstable) atoms to form atoms of lesser mass.


What is the minimum amount of unstable atoms needed to produce an uncontrolled chain reaction is called?

The minimum amount of unstable atoms needed to produce an uncontrolled chain reaction is called critical mass.


Which atoms form ions most easily?

unstable atoms


How do atoms affect the type of elements?

The number of protons equal the atomic number; the electrons from the outer shell are involved in chemical reactions. The ionization energy and the electronegativity are also important characteristics of atoms. Atoms with a big mass become unstable etc.


How do nuclear atoms differ from regular atoms?

All atoms are nuclear, in that they all have nuclei. Some atoms have unstable nuclei, making them radioactive. I'm afraid I have no idea what you mean by "nuclear atoms," unless you meant to say radioactive atoms, in which case the answer is "they have unstable nuclei and they're radioactive."

What is the primary reason an atoms nucleus is unstable?

Increasing the ratio neutrons/protons in the nucleus the atom become unstable.


Atoms that are unstable and tend to decompose to become more stable are specifically termed?

Radioisotopes.


Atoms that are unstable are more likely to be what than atoms that are stable?

Atoms that are unstable are more likely to be radioactive than atoms that are stable. This means they can emit radiation in the form of alpha or beta particles, or gamma rays, in order to reach a more stable state.


A scientists conducts a procedure that's causes nitrogen atoms to gain neutrons. the resulting atoms are?

The resulting atoms are isotopes of nitrogen, specifically nitrogen with a higher mass number due to the additional neutrons. These isotopes may be unstable and can potentially undergo radioactive decay.


Do stable atoms release nuclear particles?

No. If they did, they would be radioactive and unstable.
