What is a postively charged sub- atomic particle is called what?
There are many, but the most well known, and the one you are probably looking for, is the proton.
When an unstable nucleus produces an alpha particle by how many units does the atomic number of the nucleus change?
An alpha particle is a helium nucleus, which consists of 2 protons and 2 neutrons. When an unstable nucleus emits an alpha particle, it loses 2 protons, which means its atomic number will be reduced by 2.
What type of radiation does Radon give off?
Naturally occuring Radon gas decays by alpha particle emission. However, many of the decay chain products have very short half lives, of which some decay by alpha particle emission and others by beta particle emission.
How many protons are in an alpha particle?
The alpha particle does not have any electrons. This particle is ejected from the nucleus of an atom in what is called alpha decay, and it appears as a pair of protons and a pair of neutrons fused together. The alpha particle is a helium-4 nucleus, and soon after it appears, it will collect a pair of electrons from its environment. But as it appears in the radioactive decay process, it doesn't have any electrons.
How many protons will uranium have after releasing a beta particle?
It depends on whether the beta decay sequence is beta- or beta+. In beta-, the atom will gain a proton, changing into neptunium. In beta+, the atom will lose a proton, changing into protactinium.
When uranium (92 proton) ejects an beta particle how many protons does the remaining nucleus have?
90 protons
How many neutrons are in the above particle?
You will have to tell us what the particle is, but if it is an alpha particle, there are two neutrons in it.
How many charges does an alpha has?
+2 unit charges - the alpha particle is a helium nucleus.
What is a postively charged sub- atomic particle is called what?
There are many, but the most well known, and the one you are probably looking for, is the proton.
When the nuclei of heavy atoms with many protons are split this process is called?
Generally this is called nuclear fission. In the special case where one of the new particles produced is a Helium-4 nucleus (2 protons, 2 neutrons) the process is radioactive decay and specifically alpha emission. (The He-4 nucleus is called an alpha particle, as it was the first such particle recognized. A beta particle is an electron emitted from the nucleus with the conversion of a neutron to a proton = beta emission.)
What particle has a positive electric charge?
There are many, but the most commonly known one is the proton.
When an unstable nucleus produces an alpha particle by how many units does the atomic number of the nucleus change?
An alpha particle is a helium nucleus, which consists of 2 protons and 2 neutrons. When an unstable nucleus emits an alpha particle, it loses 2 protons, which means its atomic number will be reduced by 2.
How many nucleons does an alpha particle contain?
Four. Two protons and two neutrons.

Naturally occuring Radon gas decays by alpha particle emission. However, many of the decay chain products have very short half lives, of which some decay by alpha particle emission and others by beta particle emission.

Which subatomic particle is present in the nucleus of an atom?
The atomic particles that make up an alpha are two protons and two neutrons. The subatomic particles are contained within the neutrons & protons and there are too many to list here, plus I don't know all of them.
How many protons and neutrons are lost as U234 decays to Th230?
2 of each in the form of an alpha particle.
