atoms and 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 thr..

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 m..

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 ..

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)...
