This process changes the nuclear composition of the nucleus of an atom through an emission of particles. The type of radiaoctive decay typically depends on the particles that are converted and emitted after the reaction. Some of the common radioactive decays includ...
the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. The number of protons determines the element, but the number of neutrons in the atom of any one element can vary. Each variation is an isotope...

What is the size of the nucleus? What is nuclear fusion? What is the average atomic mass of Element X if 51.83% of Element X occurring in nature has a mass of 106.905 amu and 48.17% of the atoms have a mass of 108.905 amu? What is the molar mass of the compound C6H5CO2H? Negle...
I may be misguided here but to my understanding, separate nucleons have a higher mass altogether than the combined nucleus as the potential energy gained from being separated (in the field of the strong force) is being manifested in more mass. If this is true, and if it's not I'd like...
A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine, the rarest naturally occurring element on Earth. What is the symbol of tellurium? Tellurium is a chemical element with the sym...
The number of protons in the nucleus is called the atomic number. The atomic number of each element is unique. The combined number of protons and neutrons in an atom is called the atomic mass number. While the atomic number always stays the same. Some elements have atoms with different atom...

What happens when the nuclide astatine-218 undergoes alpha decay? What happens in alpha and beta radioactive decay? What is emitted from the nucleus during beta decay? What is the nuclear equation for beta decay of Au-198? Is energy absorbed during beta decay? What happens in the nucleus du...
When an alpha particle is emitted from the nucleus of an unstable atom, the mass number of the atom decreases by four. This is because the mass number...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer...
