Alpha particles are helium nuclei and consist of two protons and two neutrons. Their electric charge is +2 (+1 from each proton), and their mass number is 4, one for each proton and neutron. To describe their mass in other ways, it is 4.001506179125 Atomic Mass units, or 6.64465675 x 10-25 kg.

Alpha or beta types of radiation is composed of particles with a charge and mass identical to that of an electron?
beta
What are the particles emitted during radioactive decay with their mass and charge?
alpha: mass 4, charge +2beta: mass ~1/1800, charge -1gamma: mass 0, charge 0
Does alpha particles have less mass the beta particles?
An alpha particle is two protons and two neutrons (same as a Helium nucleus) so when a nucleus ejects an alpha it will defintely have less mass. Also it will be a new element because it has two less protons.
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.
Which type of radiation has no mass or charge?
Free radiation I suppose. But gamma radiation, is charge free. As is UV, IR, ... ..
What is the mass and electrical charge of alpha particles?
2.00 lbs the charge is alpha-magnetic
What particles has a mass of 4 amu and a charge of 2 plus?
An alpha particle, boom.
What is the charge of alpha particles?
+2 (2 x the absolute value of the charge of an electron).
Alpha or beta types of radiation is composed of particles with a charge and mass identical to that of an electron?
beta
What correctly describes the charge of beta particles and alpha particles?
Beta particles, from beta- decay, have a charge of -1. Beta particles, from beta+ decay, have a charge of +1. Alpha particles have a charge of +2.
What are the particles emitted during radioactive decay with their mass and charge?
alpha: mass 4, charge +2beta: mass ~1/1800, charge -1gamma: mass 0, charge 0
Would protons behave as alpha particles?
Only partially. Protons have 1/4 the mass of alpha particles and 1/2 the charge. As a result, their ability to interact with matter is less.
Does alpha particles easily absorbed?
Yes, alpha particles are easily absorbed. They have a mass of 4 and a charge of +2. As such, they easily interact, being stopped, for instance, by only a few inches of air. Compare this with the neutron (mass 1, charge 0), electron (mass 1/1836, charge -1) and the photon (rest mass 0 charge 0) and you can see an increase in penetration as you go up the scale.
Does alpha particles have less mass the beta particles?
An alpha particle is two protons and two neutrons (same as a Helium nucleus) so when a nucleus ejects an alpha it will defintely have less mass. Also it will be a new element because it has two less protons.
Alpha particles and beta particles differ in?
Alpha particles are positively charged helium nuclei while beta particle are negatively charged electrons . Alpha particle have 4u mass while beta particles have zero mass.
Why are alpha and beta rays deflected in opposite directions in a magnetic field?

Why were a few alpha particles reflected at large angles?
yes it is
