Which of the following statement is not correct?
  • a)
    Isotopes of an element have same atomic number but different mass numbers
  • b)
    The electronic configuration of isotopes of an element is different
  • c)
    The atoms which have the same mass number but different atomic numbers are called isobars
  • d)
    Two nuclei A and B are isotonic with mass numbers 15 and 16 respectively. If A contains 7 protons, then the number of protons in B would be 8
Correct answer is option 'B'. Can you explain this answer?

Which of the following statement is not correct?a)Isotopes of an eleme...
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.
