Uranium - atomic weight; 238,02891
But now it is more correct to consider plutonium as the heaviest natural element (mass: 244 for the isotope 244Pu).
A neutron is the subatomic particle with a charge of 0 and a mass of 1 atomic mass unit.
Photons and neutrinos dont have mass.
This atomic particle is the neutron.
atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons
An alpha particle is a positively charged nuclear particle consisting of two protons bound to two neutrons. The atomic number of an atom decreases by 2 and the mass number decreases by approximately 4 when an alpha particle is ejected.
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
This atomic particle is the neutron.
A neutron is the subatomic particle with a charge of 0 and a mass of 1 atomic mass unit.
Photons and neutrinos dont have mass.
This atomic particle is the neutron.
An alpha particle is a helium-4 nucleus. It has a mass of about 4 atomic mass units.
These particles are proton and neutron.
Electron
atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons
atomic mass unit
A beta particle is an electron: the mass is 5.4857990946(22)×10−4amu.
An alpha particle is a positively charged nuclear particle consisting of two protons bound to two neutrons. The atomic number of an atom decreases by 2 and the mass number decreases by approximately 4 when an alpha particle is ejected.
