Why does potassium have 9 electrons in 3rd shell?
The 3rd shell of any atom can actually contain 18 electrons, but potassium (K) normally has only one electron in the 4s orbital. To put an electron into a 3d orbital you need to reach a -2 charge, but it’s far more energetically stable for potassium to lose an electron than to gain 2.
Can there be 9 electrons in a shell?
Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on….History.
| Element | Electrons per shell |
|---|---|
| 8 | 4, 2, 2 |
| 9 | 4, 4, 1 |
| 10 | 8, 2 |
| 11 | 8, 2, 1 |
How many electrons can be in the 3rd shell?
32 electrons
The first shell (closest to the nucleus) can hold two electrons. The second shell can hold 8 electrons. The third shell can hold 32 electrons. Within the shells, electrons are further grouped into subshells of four different types, identified as s, p, d, and f in order of increasing energy.
Why does bromine have 18 electrons in its third shell?
Each shell can contain only a fixed number of electrons, up to two electrons can hold the first shell, up to eight (2 + 6) electrons can hold the second shell, up to 18 (2 + 6 + 10) can hold the third shell and so on. …
What is the electronic configuration of potassium class 9?
The electronic configuration of potassium is 2,8,8,1 and not 2,8,9.
How many electrons are there in the 3rd orbit of potassium?
18 electrons
Solution: Atomic number of the potassium = 19. Potassium has 18 electrons. Applying rule number 3, the maximum number of electrons accommodated in K shell is 2. After filling the first orbit, the second orbit will consist of 8 electrons.
Which element has 9 electrons in s orbitals?
Fluorine
Fluorine is the ninth element with a total of 9 electrons.
Which shell consist of three Subshell?
Search form
| Shell | Subshell | Total Number of Electrons in Shell |
|---|---|---|
| 1st Shell | 1s | 2 |
| 2nd Shell | 2s, 2p | 2 + 6 = 8 |
| 3rd Shell | 3s, 3p, 3d | 2 + 6 + 10 = 18 |
| 4th Shell | 4s, 4p, 4d, 4f | 2 + 6 + 10 + 14 = 32 |
Is it 8 or 18 electrons in third shell?
In this sense the third shell can hold 8 electrons. 4s2 not the third shell, but the next 10 electrons go into the 3d orbitals that are part of the third shell but shown on the fourth shell level. So the third shell can be considered to hold 8 or 18 electrons but in total the third shell can hold 18 electrons.
How do you find the electron configuration of potassium?
We’ll put six in the 2p orbital and then put the next two electrons in the 3s. Since the 3s if now full we’ll move to the 3p where we’ll place the next six electrons. We now shift to the 4s orbital where we place the remaining electron. Therefore the Potassium electron configuration will be 1s22s22p63s23p64s1.
