Are there more protons than electrons in an alpha particle?
NatalieEW
Yes.
An alpha particle is the nucleus of a helium atom, with no electrons. There are 2 protons and 2 neutrons.

Are gold atoms similar to alpha particles?
An alpha particle is the nucleus of a Helium-4 atom; therefore, it has 2 neutrons and 2 protons. A gold atom has... well, much more protons and neutrons, you can look it up if you like. Also, a gold atom normally does have electrons, whereas an alpha particle is just the nucleus (i.e., no electrons). You decide for yourself how "similar" those two are.
What particle alpha or beta is more massive?
An alpha particle is a helium nucleus, consisting of 2 protons and 2 neutrons. Beta particles are fast moving electrons that are emitted from a nucleus when a neutron decays into a proton and an electron. Since 1 electron has 1/1837 the mass of a proton, the alpha particle is roughly 7348 times the mass of the electron.
Is a ion is a charged particle because it now had either more or fewer electrons than protons?
Yes. If it has fewer electrons that protons, it will be a positively charged ion, and if it has more electrons than protons, it will be a negatively charged ion.
Is uranium-235 an alpha particle?
No. 92235U is a radioisotope with 92 protons, 143 neutrons, and (in a non-ionic, neutral state) 92 electrons. An alpha particle, on the other hand, is a helium nucleus, 24He2+ with 2 protons, 2 neutrons, and no electrons. It happens that 92235U decays by alpha decay to 90231Th with a half-life of 7.04 x 109 years, but this does not means that it is an alpha particle, it means that it emits an alpha particle. It also decays by spontaneous fission with a probability of 7 x 10-9%. It primary value, however, is that it is fissile, meaning that if it absorbs a thermal neutron, it will undergo fission, generating more neutrons, two new isotopes, and energy.
Alpha particles are positively charged. They most likely have which of these?
more protons than electrons A+
An alpha particle is identical to a?
An alpha particle is a helium-4 nucleus. It has two protons and two neutrons, and we write it like this: 24He++ or more commonly 24He2+ Some links can be found below.

What radiation does a nucleus with more than 82 protons usually emit?
An Alpha particle
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.
Particle with two protons and two neutrons ejected during decay?
An alpha particle. It is also a helium nucleus and has a charge of +2e. The ejection of an alpha particle occurs whenever the electromagnetic force overcomes the strong force in a nucleus and needs to rid itself of excess charge. The reason that a single proton is not simply ejected has to do with the stability of the alpha particle itself which is generated by the strong force. If there were more protons in an alpha particle, it would not hold together properly. It cannot have more neutrons because it simply wouldn't be ejected because of strong force.
What particle alpha or beta is more massive?
An alpha particle is a helium nucleus, consisting of 2 protons and 2 neutrons. Beta particles are fast moving electrons that are emitted from a nucleus when a neutron decays into a proton and an electron. Since 1 electron has 1/1837 the mass of a proton, the alpha particle is roughly 7348 times the mass of the electron.
What does it mean when an atom has more protons then electrons?
When an atom has more protons than electrons it is called an ion. This is a positively charged particle because it has more protons than electrons, thus the positive charge takes over.
What would happen to the overall charge if a material with a positive charge lost most of its protons and had more electrons than protons?
Its charge would be negative, since there would be more electrons than protons. However, there is no chemical process that can cause a sudden loss of a bunch of protons from the nucleus of an atom. Alpha decay can cause an atomic nucleus to expel an alpha particle, which consists of 2 protons and 2 neutrons, and there is such a thing as proton decay, but that is extremely uncommon.
Is a ion is a charged particle because it now had either more or fewer electrons than protons?
Yes. If it has fewer electrons that protons, it will be a positively charged ion, and if it has more electrons than protons, it will be a negatively charged ion.
What is am atom that has more or fewer electrons than it has protons?
The type of particle that has either more or fewer electrons than protons is an ion. Ions are called cations when they have fewer electrons than protons and anions when they have more.
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.
