example of isotopes

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

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;..

Atoms of the same element having the same atomic number but different mass numbers are called isotopes. The nuclei of these atoms have same number of protons but different number of neutrons. All the properties of the isotopes depending upon mass are different. Differen..

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)...

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..

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 neutron..

A C - 14 isotope decays from 120 gms to 80 gms in 25 days. What is the half - life of the isotope? => 49 days or 47 days or 51 days or 45 days or 43 days..
