Directions Solve the given problem below by showing the following: I ELECTRONIC CONFIGURATION
2. LED structure
GIVEN: Magnesium (Mg) and Oxygen (180).​

Explanation:

(a). Write down the electronic configuration of (i) magnesium atom, and (ii) magnesium ion, <br> (At No. of Mg=12) ,brgt (b). Write down the electronic configuration of (i) sulphur atom, and (ii) sulphide ion. <br> (At. No. of S=16).

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
