Calcium has six naturally occurring isotopes : Calcium 40, Calcium 42, Calcium 43, Calcium 44 , Calcium 46, and Calcium 48. Based on Calcium's reported atomic mass (40.078) , which do you think is the most abundant in nature ? Please Explain why

2b2t

explanation:

2b2t

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
