Which pair of ions can form an ionic bond with each other and why? cumc006-1.jpg and agmc006-2.jpg; they are both metal ions. smc006-3.jpg and omc006-4.jpg; they have like charges. brmc006-5.jpg and atmc006-6.jpg; they are both halogen ions. limc006-7.jpg and brmc006-8.jpg; they have unlike charges.

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
