Write the electronic configuration of any one pair of white tops and Square
Answers
Answer:
Isotopes:
Isotopes are atoms of the same element having the same atomic number but different atomic masses.
The difference in the masses of isotopes of an element is due to the different number of neutrons in the nucleus.
Since all the isotopes of an element have identical electronic configuration containing the same number of Valence Electrons, therefore, all the isotopes of an element show identical chemical properties.
Isobars:
Atoms of different elements with the atomic number for the same mass number are called isobars.
Isobars have different chemical properties because they have different atomic numbers & their electronic configuration is different.
