The are two isotopes having a different number of neutrons but the same number of protons.
Two different isotopes of the same atoms have the same number of protons and electrons; the number of neutrons is different.
The isotopes of molybdenum have different electron configurations.
Not; the number of protons in isotopes is identical; only the number of neutrons is different.
Two different isotopes of the same atoms have the same number of protons and electrons; the number of neutrons is different.

Nitrogen has two stable isotopes: N-14 and N-15 and 14 radioactive isotopes.
Isotopes are atoms of the same element which differ in the number of neutrons they contain. For example, helium-3 (3He), with two protons and one neutron in each nucleus, and helium-4 (4He), with two protons and two neutrons, are two different isotopes of helium. Nearly all elements found in nature are mixtures of several different isotopes. Although the chemical properties of isotopes of the same element are the same, the physical properties differ. The natural proportions of the isotopes are expressed in the form of an abundance ratio.
atomic mass.
Isotopes are atoms of the same element that have different numbers of neutrons. Different isotopes of an element have the same atomic number, but different mass numbers. I hope I helped! ^_^
Two atoms with the same number of protons but different numbers of neutrons are called "isotopes".
The number of neutrons is different.
