An element is a substance that cannot be broken down into simpler substances using ordinary chemical procedures. To disintegrate an element, procedures like nuclear reactions needed to be used.
In fact, it was thought of that the elements are indivisible during the days of Dalton, but advances in science and technology has shown that these elements could be broken down albeit not easily
The orbitals of a particular atom are not the only allowed states that an electron can take on in the atom. They are the only stable states of the atom, meaning that when an electron settles down to a particular state in an atom, it must be in one of the orbital states.
Answer:
O-18 is used as a tracer in many hydrologic studies. It is most often used as a component in a mixing-model and hydrograph separation, as O-18 acts conservatively and is applied naturally and uniformly over broad areas. O-18 can be used when different sources (old water/new water) have different isotopic values.
