Isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties. The electronic configuration of isotopes remains same because the atoms have same atomic number. Isobars are those atoms which have same mass number but different atomic number.Two nuclei will be isotone, if they have same neutron number. The mass number of the atom is equal to the sum of the number of protons and neutrons in the nucleus. A contains 7 protons, hence it will have 8 neutrons. And since A and B are isotonic, hence neutrons will be same for B too which is 8.

Statement b: The electronic configuration of isotopes of an element is different.
Explanation:
Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. This means that isotopes have the same atomic number but different mass numbers.
Isotope: Atoms of the same element that have the same atomic number but different mass numbers.
The electronic configuration of an atom refers to the arrangement of electrons in its energy levels or shells. The number of electrons in an atom is determined by its atomic number. Since isotopes have the same atomic number, they have the same number of electrons and, therefore, the same electronic configuration.
For example, let's consider the element carbon. Carbon has an atomic number of 6, which means it has 6 protons. Carbon-12 and carbon-14 are two isotopes of carbon. Carbon-12 has 6 neutrons, while carbon-14 has 8 neutrons. Both isotopes have the same electronic configuration of 2 electrons in the first energy level and 4 electrons in the second energy level.
Conclusion: The correct answer is option b) The electronic configuration of isotopes of an element is different. This statement is not correct as isotopes have the same electronic configuration due to their identical atomic numbers and electron arrangements.
