number of 4s i
n 20 = 5
20 ÷ 4 = 5
20 4s go into 80.
How many 4s are in 36
4s=20
There are no 4s in number 38.
4 x 20 = 80 4 x 19 = 76 Answer: 19 with 3 remaining
The element that completes the 4s sublevel is calcium (Ca). It has the atomic number 20, which means it has 20 electrons. The electron configuration of calcium is (1s^2 2s^2 2p^6 3s^2 3p^6 4s^2), indicating that the 4s sublevel is filled after the 3p sublevel.
How many 4s are in 36
The 4s sublevel is completed by the element calcium, which has an atomic number of 20. In the electron configuration of calcium, the 4s sublevel is filled after the 3p sublevel, resulting in the configuration of 1s² 2s² 2p⁶ 3s² 3p⁶ 4s². Therefore, the completion of the 4s sublevel occurs when two electrons occupy it.
eighteen 20 x 4 = 80 19 x 4 = 76 18 x 4 = 72
4.56
The answer is 10
