Composition of Nucleus

Two nuclei have mass numbers in the ratio $27:125$. The ratio of their nuclear radii would be:

Two nuclei have mass numbers in the ratio $8:125$. The ratio of their nuclear radii is:

Atomic number of a nucleus is $\mathrm{Z}$ and atomic mass is $\mathrm{M}$. Find the number of neutrons.

The nucleus of an atom was discovered by 

What is the size of a nucleus?

The radius $\left(R\right)$ of an atomic nucleus varies with the mass number $\left(A\right)$ as approximately $R=1.2\times {10}^{-15}{A}^{1/3}$, where $R$ is in meters. From this, one can conclude that the density of the atomic nuclei is

The density of nuclear matter as compared to the density of water is more by a factor of

As the mass number $A$ increases, which of the following quantities related to a nucleus do not change?

If the nuclear radius of  ${}^{27}\mathrm{Al}$ is $3.6 \mathrm{fm}$, the approximate nuclear radius of ${\mathrm{Cu}}^{64}$ in $\mathrm{fm}$ is;

When a $\mathrm{\beta }-$particle is emitted from a nucleus then its neutron-proton ratio-

A nucleus $X$ whose mass number is $36,$ is initially at rest. It is dis-integrated into $\alpha$ particle and a daughter nucleus $Y.$ If no $\gamma$-emmission is there, then chose the incorrect atternative.

Which of the following gives the correct number of protons and neutrons in a nucleus of carbon-$14 \left({}_6{}^{14}C\right)?$

The nucleus of an atom consists of

Which one of the following particle is unstable?

The radius of ${}_{30}{}^{64}Zn$ is about (in fm).

When atoms are bombarded with the alpha particles, only a few in a million suffer deflection and the others pass out undeflected. This is because

Atomic weight of boron is $10.81$ and it has two isotopes  ${}_5{}^{10}\mathrm{B}$ and ${}_5{}^{11}\mathrm{B}$ in nature. What must have been the ratio of number of atoms in them?

Choose the option that correctly represents the value of $1$ unified atomic mass unit $\left(1 \mathrm{u}\right)$.

Which of the following is equal to one atomic mass unit ($1 \mathrm{amu}$) ?
