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..

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 m..

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;..

: Na, Mg, K, Ca g lose electrons S, O, F, Cl g gain electrons Most of these atoms try to attain the configurations of either neon (2,8) or argon (2,8,8). By the loss or gain of electrons a neutral atom is changed to an ion . Ions are charged atoms o..

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)...

Atom Ion An atom is a neutral particle [number of e - = number of p + ] An ion is a charged particle [number of e - ≠ number of p + ] An atom is unstable. An ion is stable. An atom is incapable of in..

Isotopes - 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 n..
