isotopes and atoms

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 thr..

Isotopes of an element have same atomic number (Z) but different mass numbers (A). For example, 1 H 1 , 1 H 2 , 1 H 3 are isotopes of hydrogen;..

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 ..

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

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)...

(except helium which has two). Atoms of the same element having same atomic number but different mass numbers are called isotopes. Isotopes show similar chemical properties but different physical properties due to the difference in the number of neutron..
