What is the electronic configuration of carbon 13?
1s2,2s2,2p6,3s2, 3p1 O e. none of the above.
Which group will have an electron configuration that ends in NS 2?
The general electron configuration of all alkaline earth metals is ns2.
How many electrons would an atom need to have before it can begin filling the 3s sublevel *?
When two electrons occupy the same orbital they must spin in opposite directions—one clockwise and the other counterclockwise. b) What is the first element that has enough electrons to have one in the 3s sublevel? (Use your periodic table.) The 11th electron goes into the 3s sublevel.
What element is in group 18 Period 4?
| Period | Group | |
|---|---|---|
| 3 | Na 11 | Ar 18 |
| 4 | K 19 | Kr 36 |
| 5 | Rb 37 | Xe 54 |
| 6 | Cs 55 | Rn 86 |
What is the correct electron configuration for an atom with 7 electrons?
| Element | Atomic number | Electron configuration |
|---|---|---|
| boron | 5 | 1s22s22p1 |
| carbon | 6 | 1s22s22p2 |
| nitrogen | 7 | 1s22s22p3 |
| oxygen | 8 | 1s22s22p4 |
What is the maximum number of electrons that can fit in 3p 4f?
The 2p, 3p, 4p, etc., can each hold six electrons because they each have three orbitals, that can hold two electrons each (3*2=6).
How do you write the electronic configuration of the first 30 elements?
All of these shells are filled except the 3p shell which has four electrons. Therefore, the electronic configuration of sulfur can be written as 1s2 2s2 2p6 3s2 3p4….Electronic Configuration of First 30 Elements with Atomic Numbers.
