Order of magnitude of density of uranium nucleus is $({m_p} = 1.67 \times {10^{ - 27}}kg)$
The graph between $log\, R$ and $log\, A$ where $R$ is the nuclear radius and $A$ is the mass number is
In nuclear reactions, we have the conservation of
If the mass number of an atom is $A = 40$ and its electron configuration is $1{s^2},\;2{s^2},\;2{p^6},\;3{s^2},\;3{p^6}$, the number of neutrons and protons in its nucleus will be
Nucleus of an atom whose atomic mass is $24$ consists of
