What element has 2 electrons in the first shell and 8 in the second and 6 in the third
sulphur
Sulphur.
Sulfur
First orbital can be occupied by a total of 2 electrons and the second orbital can be occupied by a total of 8 electrons. 1s^2 2s^2 2p^6 ( what element is this ? )
There should be seven in the second shell and two in the first. The element in question is fluorine, which has the atomic number 9, the same as the number of its protons and electrons.
The answer is Sulphur
In the first shell there are two electrons and in the second shell there are six electrons, but only the electrons in the second (outer) shell are valence electrons.
Its 7Please see related link below!
Neon is the element with 10 electrons. Neon has 2 electrons in the K shell (or first energy level), and 8 electrons in the L shell (the second energy level).
lose 3 electrons from its second shell
First Shell always has 2 electrons. Second shell onwards can have up to a maximum of 8 electrons.
