Isotopes: Isotopes are the atoms of an element having same atomic number but different mass number. They also have the same number of protons . Example 1 : · Hydrogen has three isotopes : o Protium ( 1 H 1 ) : Atomic Number = Number of protons = 1, Mass number = 1 o Deuterium ( 1 H 2 ) : Atomic Number = Number of protons = 1, Mass number = 2 o Tritium ( ( 1 H 3 ) : Atomic Number = Number of protons = 1, Mass number = 3 Ex ample 2 : · Carbon has two isotopes : o Carbon-12 ( 6 C 12 ) : Atomic Number = Number of protons = 6, Mass number = 12 o Carbon-14 ( 6 C 14 ) : Atomic Number = Number of protons = 6, Mass number = 14 समस्थानिक : समस्थानिक एक तत्व के परमाणु होते हैं जिनकी परमाणु संख्या समान होती है लेकिन द्रव्यमान संख्या भिन्न होती है। उनके ...
