Explanation:
8. 3, 1, -1, +1/2 => 3pₓ¹ => Aluminum
9. 4, 2, +1, +1/2 => 4d₁¹ => Chromium
10. 6, 1, 0, -1/2 => 6p₀² => Argon
11. 4, 3, +3, -1/2 => 4f₊₃² => Lutetium
12. 2, 1, +1, -1/2 => 2p₊₁² => Neon
Percent error is [(abs(experimental - actual))/(actual)] * 100
(38.0 - 40.0 ) / 40.0 = 2.0 / 40 = 0.05
0.05 * 100 = 5
since there are 2 sigfigs, the answer is 5.0 %
I made the 2 positive since the absolute value of 38.0 - 40.0 was taken
There are only 2 sigfigs because of the subtraction of 38.0 - 40.0 gives 2.0, only 2 sigfigs
