The electron distribution in the Si atom : D. 2,8,4
Further explanation
The maximum number of electrons that can be filled in the nth electron shell is 2n²(n=shell)
- K shell (n = 1) maximum 2 x 1² = 2 electrons
- L shell (n = 2) maximum 2 x 2² = 8 electrons
- M shell (n = 3) maximum 2 x 3² = 18 electrons
- N shell (n = 4) maximum 2 x 4² = 32 electrons
Electron configuration of Si : 1s² 2s2²2p6⁶3s²3p² = 14 electron
The electron distribution :
K shell = 2
L shell = 8
M shell = 4
