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.

Explanation:
The statement that is not correct is option 'B' - "The electronic configuration of isotopes of an element is different."
Isotopes:
Isotopes are atoms of the same element that have the same number of protons (atomic number) but different numbers of neutrons (mass number). This means that isotopes have different mass numbers but the same atomic number.
Electronic Configuration:
The electronic configuration of an atom refers to the arrangement of electrons in its energy levels or shells. It is determined by the number of electrons in an atom.
Explanation of Option 'B':
The electronic configuration of isotopes of an element remains the same.
Isotopes have the same number of electrons because they have the same atomic number. The electrons are arranged in the same energy levels or shells according to the electronic configuration of the element. The only difference between isotopes is the number of neutrons in the nucleus, which affects the mass number.
For example, let's consider the element carbon. Carbon has three isotopes: carbon-12, carbon-13, and carbon-14. The atomic number of carbon is 6, which means it has 6 protons and 6 electrons.
The electronic configuration of carbon is 2, 4. This means that it has 2 electrons in the first energy level and 4 electrons in the second energy level. This electronic configuration remains the same for all isotopes of carbon.
The only difference between the isotopes is the number of neutrons in the nucleus. Carbon-12 has 6 neutrons, carbon-13 has 7 neutrons, and carbon-14 has 8 neutrons. This difference in the number of neutrons leads to different mass numbers for the isotopes.
Therefore, option 'B' is not correct because the electronic configuration of isotopes of an element is the same, while their mass numbers are different due to the different number of neutrons.
