Alpha or beta types of radiation is composed of particles with a charge and mass identical to that of an electron?
beta
Which type of particle has charge of -1 and a mass of 0?
Neutrons are particles of no charge. Electrons have negative charge.
Why are alpha and beta rays deflected in opposite directions in a magnetic field?
An alpha particle, which is a 24He nucleus, has a mass of 4 and a charge of +2. A beta particle has a charge of +1 or -1, depending on whether it is a positron (beta +) or an electron (beta -). It's mass is minuscule compared to the alpha particle, and it will undergo a comparatively huge deflection in the same field as an alpha particle would. Though the alpha particle has twice the charge as a beta particle, it has several thousand times the mass of that beta particle. As it is so much more massive than the beta particle, its inertia will be much more difficult to overcome even though it has twice the charge.
What has a negative charge and a mass of 0 amu?
beta particle
How many particles do alpha particles contain?
Beta particles have an electrical charge of -1. Beta particles have a mass of 549 millionths of one atomic mass unit, or AMU, which is about 1/2000 of the mass of a proton or neutron.
Is the beta a particle with positive electric charge?
A beta particle is an electron, and electrons are negative. You're probably thinking of a positron, which has the same mass as an electron but the opposite charge.
What will a beta particle do?
Beta particles are negatively charged are electrons and have -1 unit charge and 0 mass. They are very dangerous and have high penetrating power.
Why were a few alpha particles reflected at large angles?
yes it is
Which subatomic particles have very little mass and a negative charge-?
You're probably thinking of electrons, whose mass is much smaller than nucleons but also have a negative charge. Indeed, the electron has the smallest amount of mass of any particle with a negative charge.
Which of the subatomic particles has a negative charge is found outside of the nucleus and has almost no mass?
THe electron!
What are the properties of alpha particles?
Alpha particles are made up of 2 protons and 2 neutrons, this gives them a strong positive charge. They are slow moving and can be stopped by a sheet of paper or skin. Their charge makes them highly ionising which means that they can damage living tissue if they get inside the body. Beta Particles are made up from electrons it's charge is zero. Their mass is very light (1/1836) . Beta's penetration abilities can travel through Aluminium or a thin sheet of a metal Gamma Particles are made up from a electromagnetic wave it's charge is negative it doesn't have a mass it can travel through Lead
