The radioactive alpha particle has the same structure as the atomic nucleus of helium. They are usually formed and emitted during alpha decay.
helium nucleus
A helium nucleus (2 protons & 2 neutrons).
Alpha particles are the same size as a helium nucleus and are made up of 2 protons and two neutrons. They have no electrons so an alpha particle has a +2 charge
No Alpha radiation is essentially a helium nucleus - a couple of protons and neutrons bound together as a particle Beta radiation is an electron or positron - still a particle but not the same kind of particle as alpha.
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.
An alpha particle is a helium nucleus. It consists of two protons and two neutrons so it has mass (approximately the same as the mass of a helium atom) and charge (a plus two charge because each proton has a charge of plus one and the neutrons are not charged).
A radiation particle consisting of two protons and two neutrons is called an Alpha Particle. Alpha Particles have the same structure as a Helium nucleus. There are three forms of radiation, Alpha (Helium nucleus), Beta (a lone electron) and Gamma (an Electromagnetic wave).
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).
An alpha particle has 2 protons and 2 neutrons. That is the same as a helium nucleus.
An alpha particle is two protons and two neutrons, this is the same as a helium nucleus.
A helium nucleus (2 protons & 2 neutrons).
Helium nucleus
Alpha because it has a mass of 4
An alpha particle is the same as a helium-4 nucleus: 2 protons and 2 neutrons, all together.
2 protons and 2 neutrons. An alpha particle is the same as a helium nucleus.
an alpha particle is made of two protons and 2 neutrons. its basically the same as the nucleus of a helium atom
An alpha particle is the same as a helium nucleus. It contains 2 neutrons and 2 protons. It has no electrons, so it is not an atom.
Alpha particles are the same size as a helium nucleus and are made up of 2 protons and two neutrons. They have no electrons so an alpha particle has a +2 charge
