In a periodic table the average atomic mass of magnesium is given as 24.312 u. The average value is based on their relative natural abundance on earth. The three isotopes and their masses are `""_12^24Mg` (23.98504u), `""_12^25 Mg` (24.98584u) and `""_12^26Mg` (25.98259u). The natural abundance of `""_12^24 Mg` is 78.99% by mass. Calculate the abundances of other two isotopes.
Atomic mass unit (u) is defined as ________ of the mass of the carbon (12C) atom.
\[\ce{^197_79Au}\] contains ______.
All nuclides with same mass number A are called ______.
Nuclides with same neutron number N but different atomic number Z are called ______.
A nucleus of mass number A has a radius R such that ______.
Before the neutrino hypothesis, the beta decay process was throught to be the transition, `n -> p + vece`. If this was true, show that if the neutron was at rest, the proton and electron would emerge with fixed energies and calculate them. Experimentally, the electron energy was found to have a large range.
Two nuclei may have the same radius, even though they contain different numbers of protons and neutrons. Explain.
Which of the following are the constituents of the nucleus?
