divide 42 by 6 and get 7 so mulyiply 7 by 9
Answer:
n=3, l=1, ml=1ms=+1/2
Step-by-step explanation:
The electron configuration of chlorine atom is; [Ne] 3s² 3p⁵.
This means that the last electron is found in a 3pz orbital.
We can see that the principal quantum number is 3. The electron is in a p orbital so l=1, the electron must be found in a 3pz orbital hence ml=1. The electron is found alone in that orbital hence s= 1/2.
For the problem the Answer is ST
The ratios are equivalent because 30 * 4 is 120 and 12 * 4 is 48
Sum of interior angles of polygon is fixed for each one. 540 is pentagon in which any shape with 5 sides. Therefore the answer is the last one
