What else can I help you with?
Which atom could not emit an alpha particle?
Alpha particles consist of two protons and two neutrons (the nucleus of a helium atom). Therefore, Hydrogen is the only element that doesn't contain (and can't emit) an alpha particle.
What is an unreactive gas element that in radioactive form is a byproduct of most nuclear explosions?
Helium (or alpha particles)
Do the alpha particles in Rutherford's experiment contain electrons?
No, alpha particles are helium nuclei made up of two protons and two neutrons, with no electrons. In Rutherford's experiment, alpha particles were used to probe the structure of atoms by scattering off the positive nucleus, helping to reveal the atom's structure.
Why is it impossible for helium or hydrogen to emit an alpha particle?
Helium and hydrogen do not emit alpha particles because they contain only one or two protons in their nuclei respectively, which is insufficient for them to emit an alpha particle consisting of two protons and two neutrons. Alpha decay typically occurs in heavier elements with larger atomic numbers where the nucleus is unstable and emits an alpha particle to reach a more stable configuration.
What do alpha particles contain?
They are Helium nucleii so basically 2 protons and 2 neutrons
Do alpha particles contain helium?
No, they're just similar to a helium nucleus.
Does alpha particles contain 2 protons?
Yes, plus 2 neutrons.
Which atom could not possibly emit an alpha particle?
Helium-4 cannot emit an alpha particle, as an alpha particle is composed of two protons and two neutrons. Helium-4 already has two protons and two neutrons in its nucleus, so it cannot emit an alpha particle.
What effect does humidity have on alpha particles?
Alpha particles can be absorbed by water.
What is the electronic charge of alpha ray?
Alpha rays consist of alpha particles, which are composed of two protons and two neutrons, essentially making them helium nuclei. Since they contain two protons, alpha particles carry a positive charge of +2e, where e is the elementary charge. This positive charge is a key characteristic that differentiates alpha rays from other types of radiation.
Where could one locate Alpha particles?
Alpha particles are most commonly found when alpha decay occurs. An alpha particle is emitted during alpha decay. Further information about alpha particles can be found on the Wikipedia website.
Do amino acids contain alpha and beta pleated sheet in their secondary structure?
Yes, they do. Side group hydrogen bonding.
