isotopes of a given element have

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 ..

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

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. ..

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;..

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 b..

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)...

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..

Synthetic Elements Including Transuranics - Nuclear reactions involving the bombardment technique by different particles have been used to synthesise artificial elements such as Technetium, Astatine and Transuranium. (Z > 92) which follow uranium in the periodic table. The nucle..
