Are neutrons and electrons in radioactive isotopes?
Because the structure of their nuclei is unstable: too many or too few neutrons, excess energy causing metastable state, etc. To get more stable they decay, emitting alpha, beta, and/or gamma radiation.
What is the collective name of high-energy particles and rays given off by the nuclei of atoms?
The energy is called nuclear radiation, high energy particles and rays that are emitted by the nuclei of some atoms.
What subatomic particles are first to contact each other when two atoms come togehter?
It is not possible for two particles to touch (via the Pauli Exclusion Principle, which states that two fermions are not able to occupy the same quantum state); however they will interact. In the case of atoms, assuming that they are not merely nuclei, the electrons will interact first via the electromagnetic or weak force.
What is the process of joining two nuclei together to form a new element called?
Joining two nuclei to produce an atom of a different element is called fusion.
How do molecules produce spectral lines unrelated to the movement of electrons between energy levels?
The nuclei also interact with each other (being charged particles) and therefore have energy levels which can decay to produce photons.
What is a process in which atomic nuclei of unstable isotopes release fast-moving particles and energy?
Radioactivity
What is the process in which the nuclei of unstable atoms can become more stable by emitting particles or electromagnetic radiation?
The process described is radioactive decay.
Are beta particles the same as helium nuclei?
B- particles are electrons. They are not Helium nuclei.
A process in which atomic nuclei of unstable isotopes release fast-moving particles and energy?
Nuclear fission
Why did the path of only some alpha particles deviate in Rutherford experiment?
Alpha particles are positively charged helium nuclei. As such, they are repelled by other positively-charged nuclei. In Rutherford's experiment, he used gold foil. Since gold atoms have large, massive nuclei, the alpha particles were easily repelled by the large gold atom nuclei, and they were scattered in different directions.
What is radiactivity?
Radioactivity refers to the particles which are emitted from nuclei as a result of nuclear instability. It is also known as a decomposition process.
Why beta has the least penetrating power?
It is not clear what is meant by 'beta'. Please rephrase it in a new question. It's pretty obvious this question is about radioactivity and the beta particles produced by that. In fact beta particles are not the least penetrating. It is the alpha particles that penetrate least. That's because they interact easily with atomic nuclei. Atomic nuclei are positively charged, like alpha particles, causing strong repulsion.
Are neutrons and electrons in radioactive isotopes?
Because the structure of their nuclei is unstable: too many or too few neutrons, excess energy causing metastable state, etc. To get more stable they decay, emitting alpha, beta, and/or gamma radiation.
What is the process in which the atomic nuclei of unstable isotopes release fast moving particles and energy?
radioactive decay or simply decay.
Particles that do not usually act as condensation nuclei are?
Ozone Particles
Which particles is similar to a He nucleus?
The so-called alpha particles ARE helium nuclei.
Alpha particles ejected from the nucleus travel at the speed of light?
No. Alpha particles are helium nuclei; such nuclei have a mass, and can therefore NOT travel at the speed of light.
