The commonest use of alpha particles is probably in smoke detectors. The americium in the smoke detectors emits alpha particles. If smoke is present, it stops the alpha particles more efficiently than air, creating ions in the detection area of the device. The ions make the air more conductive, and the conductivity is sensed by the detector, which sets of the alarm.
Alpha particles are also used in the radioisotope thermoelectric generators that power pacemakers and space probes.
What else can I help you with?
What neutrons are in an alpha particle?
A nucleon is the amount of protons and neutrons. An alpha particle has an atomic number of 2 and a atomic mass of 4 then it has 2 protons and 2 neutrons.There are 4 nucleons in an alpha particle.
Symbol and charge of alpha particle?
The charge of an alpha particle is 2+ and the symbol is α2+.
Are alpha particle negative or positive?
An alpha particle is a helium nucleus; it has a charge of +2.
What is an alpha particle equivilent to?
An alpha particle is equivalent to a helium-4 nucleus, or a helium-4 ion. A difference is that an alpha particle has a certain amount of energy associated with it, so it can said to be fast or hot. The energy is measured in thousands or millions of electron volts (keV or MeV).
What is the particle charge of an electron?
The chaarge of an alpha particle is +2.
How manyneutrons are in an alpha particle?
There are 2 neutron in an alpha particle.
Which of these masses is the largest alpha particle antineutrino gamma radiation beta particle?
Alpha Particle
Is alpha particle non fundamental?
Yes, the alpha particle is nonfundamental.
What is a subatomic particle with two neutrons that is emitted during some types of radioactive decay called?
This would be the alpha particle. An alpha particle has two neutrons and two protons, and it's actually a helium-4 nucleus. That's why we write this particle like this: 42He or He+2 Use the links below for more information.
What is the electrical charge of an alpha particle?
The electric charge of an alpha particle is positive. An alpha particle is a helium nucleus (which being a nucleus has a positive charge)
How do the mass and size of an alpha particle compare with mass and size of beta particle?
The mass and size of an alpha particle compare with the masa and size of beta particle in the sense that the alpha particle is significantly larger in both size and mass that the beta and gamma particles. This is why it is called the alpha particle.
Is an alpha particle is identical to the nucleus of a?
An alpha particle is identical to the nucleus of Helium atom
What is the charge of an alpha particle?
An alpha particle has a charge of 2, which means it is positively charged.
What neutrons are in an alpha particle?
A nucleon is the amount of protons and neutrons. An alpha particle has an atomic number of 2 and a atomic mass of 4 then it has 2 protons and 2 neutrons.There are 4 nucleons in an alpha particle.
Is the particle with a plus 2 charge a an alpha particle b a gamma ray or c a beta ray?
a. an alpha particle
Is alpha particle is heavy particle?
An alpha particle is a helium-4 nucleus. It has a mass of about 4 atomic mass units.
What is the charge of the emitted particle in alpha decay?
In alpha decay, the emitted particle has a charge of 2.
