How many protons are in a neutron?
Technically they are two totally different particles. That being said, in beta emission a neutron is converted into a proton and an electron is released.
How many number of neutrons in helium 3?
1 neutron It has in its nucleus 1 neutron and 2 protons so its mass number is 3, hence whay it is called helium-3. (Mass number = # of protons + # of neutrons)
What is tha neutron for calicum?
An atom contains protons, neutrons, and electrons. The electrons are tiny. They can be found in a fast-moving cloud, orbiting the nucleus. Each electron has a charge of -1. The nucleus contains the protons and neutrons, which are packed tightly together. The protons each have a charge of +1, and the neutrons have a charge of zero. The mass number of an element is the number of protons and the number of neutrons added together. Since the number of protons is equal to the atomic number of the element, the number of neutrons can be found by subtracting the atomic number from the mass number.
How many protons neutrons and electrons are in gadolinium?
Proton: 64 Electron: 64 Neutron: 93 if my math is correct
Is protactinium a metalloid?
Protactinium is a metal.
When uranium 238 changes into protactinium 234 how many protons does it lose?
Uranium-234 become protactinium by emission of a beta particle. A proton is transformed in a neutron.
Chemistry how many protons does a protactinium has?

How many protons and electrons does a neutron have?
None. Protons and electrons are not constituents of a neutron. Both neutrons and protons are constituents of an atom's nucleus (core), while the electrons are situated in the electronic cloud around the nucleus.
How many protons and how many neutrons in the nucleus of a helium 4 atom?
