The most abundant isotope is $^{63} A$ $""^63A$ .

Explanation:

The average isotopic mass is the weighted average of the mass of the individual isotopes. Because the quoted average, $63.6$ $63.6$ $amu$ $"amu"$ , is closer to $^{63} A$ $""^63A$ than $^{65} A$ $""^65A$ , the $^{63} A$ $""^63A$ isotope is the more abundant. Can you tell us which metal this element is?
