Why are alpha particle tracks observed in a cloud chamber much shorter than beta particle tracks though they emerge from a radioactive sample with almost the same speed?

Alpha particles have a mass of about 4 and a charge of +2, while beta particles have a mass of about 5x10-4 and a charge of -1. As such, the alpha particle interacts much more easily than the beta particle, and spends its energy more quickly.

Why do alpha particles travel shorter distance in air than beta particles?
because alfa particle have a tendency to move in air then beta particles
Is samarium radioactive?
There are seven naturally occurring isotopes of samarium (Sm), and they are Sm-144 Sm-147, Sm-148, Sm-149, Sm-150, Sm-152 and Sm-154. Samarium's radionuclides Sm-147, Sm-148, and Sm-149 are alpha emiters. That is, they emit helium nuclei. The other isotopes are stable. A link can be found below.
Should Radioactive isotopes used for medical purpose have long lives?
Radioactive isotopes used for medical purpose should not have long lives. The imaging cameras need to pick up the particles from the decay of the radioactive nuclei, and having a lot within an hour or two means a short half-life.
Do longer or shorter restriction fragments travel farther?
shorter
Whose faster between a taller person or a shorter person?
Shorter
Can a cloud chamber be used to detect radioactivity?
Yes. A cloud chamber can detect alpha and beta particles that emanate from various radioactive decay processes. This works because the cloud chamber is a sealed environment containing a supersaturated vapor of water or alcohol, and when ionizing radiation enters the chamber, the charged particles interact with the vapor, forming a mist (cloud), which is actually just a condensation trail. You can identify alpha or beta by looking at the thickness and length of the trail, alpha being thicker and shorter than beta, and you can identify charge by applying a magnetic field across the chamber, causing plus charges to curve one way and minus charges to curve the other way.
What are the unstable element?
Radioactive elements are unstable, and the shorter the half-life, the more unstable they are.
How does hybridisation effect bond length?
simple rule is that the more s character in the hybrid orbital the smaller it is and therefore the shorter the bond it will make. Soem of the shortening observed in double bonds is due to this effect. sp shorter than sp2 shorter than sp3

Is neodymium radioactive?
Neodymium is radioactive, though for most practical purposes it can be regarded as stable. 30.4% of neodymium is of two radioactive isotopes, but their half lives are very long, the shorter being 2,290,000,000,000,000 years. Like all other elements, neodymium has synthetic radioactive isotopes.
What is the difference between the .223 and 5.56 NATO round?
The 5.56 NATO round is a tad longer, about 0.4mm longer; but that has nothing to do with why you shouldn't intercnahge them. You shouldn't mix them because a 5.56 NATO chamber has a longer leade (cartrige mouth to rifleing engagement), a .223 chamber has a shorter leade. Shooting .223 out of a 5.56 chamber will not lead to any problems other than less-than-stellar acuracy, however, usind 5.56 in a .223 chamber WILL lead to premature wear out of the chamber and parts.
Why Radioisotopes in nuclear medicine are desirable to have shorter half lives?
A short half-life means the material only remains radioactive for a short time and does not continue to release radiation into the patient or environment.
Why is the half life of an element important?
The shorter the half-life the greater the danger of radiation causing us harm. If you have two equal masses of radioactive material with different half-lives, the one with the shorter half-life will release more radioactivity in a given time than the one with the longer half-life.
Can you shoot 357 magnum shells in a 357 maximum rifle?
Yes, however, they may not cycle thru, and need to be loaded one at a time. Chamber will need cleaning after shooting the shorter magnum cartridge.
Can you shoot 38 plus p in a 357 magnum?
A .357 Magnum firearm is more than capable of handling the chamber pressure generated by the .38 Special +P ammo. However, this only applies to revolvers - in a magazine fed .357 firearm, the shorter .38 Special cartridges will not achieve proper headspacing in the chamber.
What is the other name for Mani?
Mani is the shorter name for Subramanian. I've observed this for quite some time now .. people with the name Subramanian , Subramaniam etc like to be called Mani. Hope this helps =)
List of radioactive elements?
Elements that decay (give off protons and neutrons) to form other elements. *It's not elements as such that are stable or unstable, but rather isotopes. Even elements of small atomic number have unstable isotopes that undergo radioactive decay, for example carbon-14. Elements with higher atomic numbers than Lead (82) are naturally radioactive in all isotopes. Bismuth (83) has an extremely long half-life, but the time generally becomes shorter (the decay more rapid) as the size of the nucleus gets progressively larger for heavier radioactive elements.
