Which equation correctly represents the electron affinity of calcium? a) ca(g) + e- > ca- (g)b) ca (g) --> ca+ (g) +e-c) ca (g) > ca- (g) + e-d) ca- (g) > ca (g) + e-e) ca+ (g) + e- > ca (g)

Explanation:

The electron affinity is the energy released in addition of one electron to an isolated gaseous atom (for neutral atom).

Thus the atom in the equation should be gaseous

The reaction should show addition of electron in the atom

After addition of electron the product will be a negative gaseous ion (mono negative).

Thus the equation will be:

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
