sulfur
Sulfur is most commonly referred as a foul smelling element.
An element that is a yellow solid and found as an impurity in coal is sulfur. Sulfur is one reason why burning coal creates pollution. When impure coal is burned, sulfur dioxide is created and contributes to phenomena such as acid rain.
it is combined of a three carbon element and then combined with a four carbon element and the made into citric acid.
Copper
Synthesis
Hydrogen
If the impurity is of type "n" - an element (the impurity) that has 5 electrons in its outer shell - conduction will be mainly via electrons. If the impurity is of type "p" - the atoms of the impurity has 3 electrons in its outer shell - the conduction will be mainly via holes.
Silicon has 4 valence electrons. When a penta-valent impurity like phosphorus is added, conduction takes place through the excess electron, the donor. Arsenic is another good example of a donor impurity
Sulfur is most commonly referred as a foul smelling element.
Oxygen combined with one other element is an oxide.
When one element is combined with another element, a chemical compound results. The elements are chemically bonded together to make this compound.

will there be any structural changes when divalent is doped with trivalent
it is combined of a three carbon element and then combined with a four carbon element and the made into citric acid.
If there are two or more elements or compounds physically combined, then it can no longer be an element.
This element is sodium (Na).
Thorium is a natural chemical element.
