Two, Eight and Eighteen
Added:
The maximum number of electrons in all (1-7) shells (or periods I to VII) of the common Periodic Table of elements:
First K-shell: 2
Second L-shell: (2)+6= 8
Third M-shell: (2+6)+10= 8+10= 18
Fourth N-Shell: (2+6+10)+14= 18+14= 32
Fifth O-shell: .........................= 32+18= 50 (in common periodic table: max. reached at 32)
Sixth P-shell: .........................= 50+22= 72 (max. reached at about 18)
Seventh Q-shell: (2+6+10+14+18+22)+26= 72+26= 98 (max. reached at 2)
It is amazing to see the regularity and periodicity of these maximum numbers of electrons.
Would Mendeleev have expected anything like this when he came to his first idea's on 'arranging elements in a table' like he did and has got the Nobel Prize for Chemistry 1906 for.
This element is sulfur (S), with 2 electrons in the first shell, 8 electrons in the second shell, and 6 electrons in the third shell.
First Shell always has 2 electrons. Second shell onwards can have up to a maximum of 8 electrons.
Sulfur has six electrons in its third electron shell.
What element has 2 electrons in the first shell and 8 in the second and 6 in the third
The first shell can have 2 electrons, the second shell has 8 electrons and the third shell has 8 electron also. No matter what, electron fill up the first shell and then move into the next shell and then the next one. To answer the question, the first shell would have 2 electron and then the second shell would have six.
This element is sulfur (S), with 2 electrons in the first shell, 8 electrons in the second shell, and 6 electrons in the third shell.
First Shell always has 2 electrons. Second shell onwards can have up to a maximum of 8 electrons.
It depends what electronic state it's found in, but in it's ground state (natural form) it has two electrons in the first shell, eight in the second and none in the third. This is because it has an atomic number of 10. 2+8 = 10.
Sulfur has six electrons in its third electron shell.
Sulfur
The first shell can hold a maximum of 2 electrons, the second shell can hold up to 8 while the third shell can also hold a maximum of 8.
It is sulphur.

What element has 2 electrons in the first shell and 8 in the second and 6 in the third
No, its two electrons in the first, 8 electrons in the 2nd and 3rd shell if its stable
Silicon.
