This depends on the velocity, or temperature, of the alpha particle. The faster the particle goes, the higher its temperature, and the more energetic it is. When we are dealing with atoms and subatomic particles, temperature and velocity are pretty much measurements of the same thing.
Most alpha particles emitted from large radioactive atoms have energies in the range of 3 to 7 MeV (million electron volts). Alpha particles from the decay of the heavier, man-made atoms can be more energetic yet. 5 MeV would mean that the particle is going about 15,000 km/s, or about 5% of the speed of light. At that speed, the alpha particle can be absorbed by a piece of thin paper.
They are not horribly dangerous, if the particles are outside you. But if they are emitted from something inside you, they can be very destructive because they can alter living cells.
It should be noted that an alpha particle is essentially the same thing as a Helium-4 nucleus. The difference is that the alpha particle came from nuclear decay, and is moving.
What else can I help you with?
Does an alpha particle and beta particle has the same speed in a magnetic field?
Alpha particles with the same energy as beta particles have much less speed, magnetic field or no.
How much alpha particle is heavier than neutron?
An Alpha particle is composed of two protons and two neutrons, so simplisticly it is heavier than one neutron by the mass of two protons and one neutron. A proton weighs in at 1.672621777(74)×10−27 kg and a neutron a bit more at 1.674927351(74)×10−27 so you can do the maths if u want to see the actual figure.
Which type of nuclear substance is a helium nucleus?
The alpha particle has a composition identical to a helium nucleus, specifically, the nucleus of helium-4. The alpha particle, however, is a product of radioactive decay, and is usually moving pretty fast. When we speak of helium nuclei, we are usually speaking of things that are much less energetic.
Is an alpha particle lighter than an electron?
No, an alpha particle is not identical to an electron. An alpha particle is a helium-4 nucleus, and it's composed of a pair of protons and a pair of neutrons fused together. It several thousand times the mass of an electron, and has twice its charge with an opposite sign (+2). An electron is that little negatively charged (-1) elementary particle that we find whizzing around atoms. You'll find a pair of related questions linked below.
Does a beta particle have a zero charge?
The particle that carries the positive charge (a proton) is much more massive than the particle that carries the negative charge (an electron) The charges are equal in magnitude though of opposite polarity.
Which has the largest mass alpha particle gamma ray positron or beta particle?
The alpha particle is much more massive than a beta particle. A beta particle is an electron, which has very little mass. An alpha particle is a helium nucleus, and consists of two protons and two neutrons.
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.
Does an alpha particle and beta particle has the same speed in a magnetic field?
Alpha particles with the same energy as beta particles have much less speed, magnetic field or no.
What is musculear strength?
How much force you can exert at one time.
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.
How much force does one exert when lifting an object?
The force would be the weight of the object.
How much force can you exert on a piece of paper?
As much as is available. That of course does not mean the paper can withstand it.
How much force does a train exert while in motion?
The force exerted by a train while in motion depends on its weight and speed. Trains can exert thousands of pounds of force, enough to move heavy loads and passengers.
How much alpha particle is heavier than neutron?
An Alpha particle is composed of two protons and two neutrons, so simplisticly it is heavier than one neutron by the mass of two protons and one neutron. A proton weighs in at 1.672621777(74)×10−27 kg and a neutron a bit more at 1.674927351(74)×10−27 so you can do the maths if u want to see the actual figure.
Why wouldn't the electrons int the atoms of the gold foil affect the paths of the alpha particles?
For much the same reason a car's path isn't affected much by someone throwing a pillow at it.Electrons are on the order of 7500 times less massive than an alpha particle; hitting them makes almost no difference to the motion of the alpha particle.
How much force did the puck exert on the hockey stick at 0.200kg in a 6ms in 2 seconds?
Not that much actually.
Which type of nuclear substance is a helium nucleus?
The alpha particle has a composition identical to a helium nucleus, specifically, the nucleus of helium-4. The alpha particle, however, is a product of radioactive decay, and is usually moving pretty fast. When we speak of helium nuclei, we are usually speaking of things that are much less energetic.
