Expanded Notation of 65 = (6 x 10) + (5 x 1).
65
65 million = 65,000,000
The isotopic notation of copper-65 is written as ( ^{65}_{29}\text{Cu} ). In this notation, 65 represents the mass number, which is the total number of protons and neutrons in the nucleus, and 29 is the atomic number, indicating the number of protons in copper. This notation helps distinguish copper-65 from other isotopes of copper, such as copper-63.
6.5 = (6 x 1) + (5/10)
a number plus 65

65 million = 65,000,000
The isotopic notation of copper-65 is written as ( ^{65}_{29}\text{Cu} ). In this notation, 65 represents the mass number, which is the total number of protons and neutrons in the nucleus, and 29 is the atomic number, indicating the number of protons in copper. This notation helps distinguish copper-65 from other isotopes of copper, such as copper-63.
The isotope notation for an element with atomic number 29 (Z=29) could be represented as follows: Cu-63 or Cu-65, where Cu is the chemical symbol for copper.
