about isotopes

Isotopes are atoms of the same element having different atomic mass but same atomic number. For e.g., there are three isotopes of hydrogen with atomic mass 1, 2, and 3. According to Mendeleev's periodic table these should be placed at three separate places. However isotope..

Isotopes - It is interesting to note that atoms of a given atomic number can have different number of neutrons. Some examples are listed belo..

These are the elements having same atomic number but different mass number. They have the same atomic number because the number of protons inside their nuclei remains the same. The difference in their mass number is due to the difference in their number of neutrons. Since they are neutral iso..

All isotopes of an element have the same number of valence electrons thus have identical chemical properties. The physical properties of the isotopes are different due to the difference in the number of neutrons in their nuclei. The densities, melting points and boiling poi..

All isotopes of the same element have the same number of protons, but a variable number of neutrons. The isotopes of hydrogen have the following structures (Fig.9.1)...

All isotopes of a substance have the same chemical properties and behave in an identical manner. The advantage of a radioisotope is that its position can be detected very easily by the radiation which it emits. It has wide applications in various fields lik..
