The approximate radius of a H-atom is `0.05` nm, and that of proton is `1.5 xx 10^-15` m. Assuming both hydrogen atom and the proton to be spherical, calculate fraction of the space in an atom of hydrogen that is occupied by the nucleus.

Calculate the mass of 12.0 xx 10^(14) atoms of hydrogen .

The radius of a hydrogen atom is 5.32 xx10^(-11) m and the radius of a proton at the centre is 1.5 xx 10^(-5) m. The ratio of the radius of the atom to the radius of proton is :

The nucleus of an atom can be assumed to be spherical. The radius of the nucleus of mass number-A is given by (1.25xx10^(-13)) cm. Radius of atom is one A. If the mass number is 64 then the fraction of the atomic volume that is occupied by the nucleus is

The ratio of the radii of hydrogen atom and its nucleus is ~ 10^(5) . Assuming the atom and the nucleus to be spherical. (a) What will be the ratio of their sizes ? (b) If atom is represented by planet earth 'R_(e)' = 6.4 xx 10^(6)m , estimate the size of the nucleus.

The ratio of the radii of hydrogen atom and its nucleus is ~ 10^(5) . Assuming the atom and the nucleus to be spherical. (a) What will be the ratio of their sizes ? (b) If atom is represented by planet earth 'R_(e)' = 6.4 xx 10^(6)m , estimate the size of the nucleus.

Nuclear radius is of the order of 10^(-13) cm white atomic radius is of 10^(-8)cm .Assuming the nucleus and the to be spherical .What frection of an atom is occupted by nucleus ?

The nucleus and an atom can be assumed to be spherical. The radius of atom is on Å if the mass number is 64, the fraction fo the atomic volume that is occupied by the nucleus is:
