New discoveries of positrons mesons neutrinos and others are usually called what particles?
New discoveries of particles like positrons, mesons, neutrinos, and others are typically classified as "subatomic particles." These particles fall under various categories, including elementary particles and composite particles, depending on their structure and properties. They play crucial roles in the field of particle physics, contributing to our understanding of the fundamental forces and constituents of matter.

Positrons mesons neutrinos and others are usually called?
subatomic particles :)
What does an unstable nucleus emit?
An unstable nucleus (radioactive isotope) may emit: alpha particles, beta particles, gamma radiations, electrons, positrons, X-rays, and neutrons, depending on which nucleus is doing the emitting.
What are Waves usually given off during nuclear reactions?
Three common types of waves given off during nuclear reactions are gamma rays, alpha particles, and beta particles. Gamma rays are high-energy electromagnetic radiation, alpha particles are helium nuclei consisting of two protons and two neutrons, and beta particles are high-energy electrons or positrons.
Are the particles in a liquid are usually closer together than the particles in a solids?
No, the particles in a solid are usually closer together than the particles in a liquid. In a solid, the particles are tightly packed and have a fixed position, while in a liquid, the particles are more loosely packed and can move around.
Quantum uncertainties are most predominant for simultaneously measuring the speed and location of?
Quantum uncertainties are most predominant for simultaneously measuring the speed and location of subatomic particles, such as electrons. This is characterized by the Heisenberg Uncertainty Principle, which states that the more precisely one of these properties is measured, the less precisely the other can be known.

Will electrons will be emitted in a radioactive decay?
It does not usually involve the atom's electrons, except for a type of decay called K capture. But the beta particles ejected in what is called beta decay are either electrons or positrons.
What does an unstable nucleus emit?
An unstable nucleus (radioactive isotope) may emit: alpha particles, beta particles, gamma radiations, electrons, positrons, X-rays, and neutrons, depending on which nucleus is doing the emitting.
What is a lepton?
Leptons are (as far as we know) fundamental particles, meaning that as far as we know, there are no particles that make up leptons themselves. (Leptons are not the only fundamental particles; they are just a class of fundamental particles.) They have no strong interactions, meaning that they cannot experience the strong force (the strong force is the force that holds the nucleus of an atom together, and the force that holds the quarks inside of protons and neutrons). There are six known leptons: electrons, electron neutrinos, muons, muon neutrinos, taus, and tau neutrinos. Electrons are probably the most familiar leptons. You may have learned about electrons "orbiting" the nucleus of an atom. ("Orbiting" is in quotes because that is only a rough approximation of what electrons do. In realty, electrons act more like waves oscillating, or vibrating, in an atom than like particles orbiting the nucleus of an atom.) Muons and taus are heavier than electrons and are also unstable. Muons and taus decay within a tiny fraction of a second, usually into a combination of electrons and neutrinos. Neutrinos have zero electric charge and very little mass. Since neutrinos have no electric charge, they are only affected by the weak force and the force of gravity. This means that neutrinos don't interact with other particles very much. In fact, there are thousands of neutrinos passing through you (without interacting with the particles in you) right now! As for now, scientists have determined that leptons have no internal structure or even size. (That doesn't make much sense; how can something not have size? But remember leptons aren't made of anything as far as we know. It wound't make sense for something not made of anything to have size... Quantum mechanics and particle physics can get confusing.) It is possible that future research may prove this to be false, showing that there is substructure within the particles, but for now leptons are considered to be fundamental particles. A current theory that would explain what leptons (and everything else) is made of is string theory. This theory basically says that everything is made up of "strings" of energy. (This still doesn't really help in determining the size of a lepton. If a leptons is made up of energy, how much space does that energy take up? But does energy even take up space...?)
Beta radiation is made up of what?
There are 3 different types of radioactive decay. alpha decay, beta decay and gamma decay. alpha decay is composed of a helium nuclei, beta decay emit either electrons or positrons, and finally gamma decay in which high energy "rays" of photons. A positron is a positively charged electron (antimatter twin of the electron). See the natural decay series of U-238 and others to see which daughters emit beta to alpha or gamma. there is also the neutrino. I cant say we really know that much about it but basically it helps satisfy the law of conservation.

Gamma rays are high-energy electromagnetic radiation, alpha particles are helium nuclei consisting of two protons and two neutrons, and beta particles are high-energy electrons or positrons.
Do All the subatomic particles participate in chemical reactions?
No, not all subatomic particles participate in chemical reactions. The main particles involved are protons, neutrons, and electrons. Protons and neutrons are found in the nucleus of an atom and contribute to its mass, while electrons are involved in forming chemical bonds with other atoms. Other subatomic particles, such as neutrinos and muons, do not play a significant role in chemical reactions.
Is radioactivity natural?
yes, radioactivity is natural. It is the natural process by which elements having neutron-proton ratio more than 1.5 disintegrate the nucleus to release particles like alpha particles, beta particles, gamma rays, positrons etc. This process continues until the nucleus of the atom is stable with the neutron-proton ration less than or equal to 1.5. Usually the natural process of radioactivity ends with the formation of Lead.
How do scientists tell people about their discoveries?
Usually in a scientific journal.
Particles that do not usually act as condensation nuclei are?
Ozone Particles
Are the particles in a liquid are usually closer together than the particles in a solids?
No, the particles in a solid are usually closer together than the particles in a liquid. In a solid, the particles are tightly packed and have a fixed position, while in a liquid, the particles are more loosely packed and can move around.
Are accidental discoveries are good as non-accidental ones?
Most great discoveries started out as accidental. The discoverer usually wondered why something happened and began investigating and experimenting to learn about it.
