Two nuclei have their mass numbers in the ratio of $1 : 3.$ The ratio of their nuclear densities would be
${\left( 3 \right)^{\frac{1}{3}}}:1$
$1:1$
$1:3$
$3:1$
An alpha particle is projected towards a stationary ${}_{92}^{235}U$ nucleus with $KE$ kinetic energy find distance of closest approach
Explain by illustrating the types of atoms.
The nuclei ${ }_{6} C^{13}$ and ${ }_{7} N^{14}$ can be described as
Read the following statements:
$(A)$ Volume of the nucleus is directly proportional to the mass number.
$(B)$ Volume of the nucleus is independent of mass number.
$(C)$ Density of the nucleus is directly proportional to the mass number.
$(D)$ Density of the nucleus is directly proportional to the cube root of the mass number.
$(E)$ Density of the nucleus is independent of the mass number.
Choose the correct option from the following options.
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
