The true statement for nuclear model for the atom is B: For a given element, the size of an atom is the same for all of the element's isotopes is

Explanation:

The isotopes are the atoms of an element that have different number of neutrons in their nuclei but same number of electrons.

The number of protons remains the same in isotopes.

the atomic mass of the isotope differ because the atomic mass is number of proton + number of neutrons.

The atomic number remains the same since number of protons equals the number of protons.

The atomic radii does not change because the arrangement or number of electrons do not differ among the isotopes. Since there is no change in atomic radii the size remains same in isotopes of an element. Although the size of nucleus increases due to more protons.
