Atoms of the same element cannot have different physical and chemical properties, but can have varied number of neutrons in their nucleus. Technically, the correct answer would be true.
All the atoms of an element have the same physical and chemical properties. However, the existence of isotopes showed that some atoms of the same elements have different number of neutrons in the nucleus, even though the number of protons and electrons remain the same.
The varied number of neutrons in the isotopes of the same element, however, does not alter the physical and chemical properties of the isotope.
