What else can I help you with?
Which term is defined as the emission of energy from subatomic particles?
Radiation
Who said atoms were made up of subatomic particles?
Rutherford proved it it from his alpha-particle scattering experiment.
Do nuetrons have higher mass or alpha particles?
alpha particles consist of two protons and two neutrons (helium nucleus) logically one neutron can not have a larger mass than two neutrons and two other subatomic particles of a similar mass
Particles consisting of two protons and two neutrons?
Alpha particles, which are common in nuclear reactions, consist of two protons and two neutrons bound together. They have a positive charge and are relatively heavy compared to other subatomic particles. Alpha particles are commonly emitted during radioactive decay processes.
Is alpha particle visible or invisible?
Alpha particles are not visible to the naked eye as they are subatomic particles. They are positively charged and have low penetrating power, so they can be stopped by a piece of paper or a few centimeters of air. Detection of alpha particles typically requires specialized equipment.
How the 3 subatomic particles discover?
Subatomic particles were discovered through experiments involving the interaction of matter with various forms of radiation, such as beta particles, gamma rays, and alpha particles. Scientists like J.J. Thomson, Ernest Rutherford, and James Chadwick played integral roles in the discovery of electrons, protons, and neutrons, respectively. Their contributions to the field of atomic and nuclear physics helped unravel the nature of subatomic particles and their properties.
Which term is defined as the emission of energy from subatonic particles?
Radioactivity is the term defined as the emission of energy from subatomic particles, such as alpha particles, beta particles, and gamma rays. These emissions occur from the spontaneous decay of unstable atomic nuclei.
Who identified cathode rays as subatomic particles?
J.J. Thomson is credited with identifying cathode rays as streams of negatively charged subatomic particles, which were later named electrons. His experiments with cathode ray tubes led to the discovery of the electron and contributed to the development of the atomic theory.
Which type of nuclear radiation (nuclear emission) has the greatest mass?
Alpha or an He nucleus because it has a mass of 4 when all the others have a mass of close to zero.
An alpha particle is composed of which subatomic particles?
A Helium Nucleus so 2 protons and 2 neutrons Quarks are contained within the neutrons & protons and there are many types
What is the greatest amount of mass a radioisotopes emits?
The amount of mass a radioisotope emits is typically very small, on the order of atomic or subatomic particles such as alpha or beta particles. These emissions do not significantly affect the overall mass of the radioisotope.
What effect does humidity have on alpha particles?
Alpha particles can be absorbed by water.
