shell elements are three or four sided entity, used to represent a part or all of a structural component that has a thickness much smaller than the other two dimensions.
The outermost shell of an element, called the valence shell, determines the chemical properties of the element. The number of electrons in the valence shell influences how atoms bond with other atoms to form molecules.
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.
No, oxygen, as a nonmetal element, cannot have an expanded octet in its valence shell.
The key to "happiness" for an atom is a full outer electron shell. (The outer electron shell is called the valence shell.) There are two conditions that cause a shell not to be full. Either it has only an electron or two (or three) in the outer electron shell or it's short an electron or two in that outer shell. The direct answer to the question is that if an element is chemically active, its outer electron shell is incomplete or is not full.
If the number of electrons in the M shell is equal to the sum of the electrons in the K and L shells, then the element is Silicon (atomic number 14). It has 4 electrons in the K shell, 8 in the L shell, and 2 in the M shell.
It is sodium Chlorine is the first element that needs a third shell.

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.
The element with 4 valence electrons in the 6th shell is lead (Pb). Lead has 4 electrons in its outermost shell, which is the 6th electron shell.
No, oxygen, as a nonmetal element, cannot have an expanded octet in its valence shell.
sulphur
This is an ionic bond.
Sulfur
an element is stable when it has a full outer shell of electrons. to abide by the octet rule it must have a shell of 2 then 8 electrons. An element with a full outer shell (8) will be stable and act like its nearest noble gas.
