Interpretation:
Concerning in Earth’s crust the atom percent elemental abundance, the statement that is incorrect has to be chosen from the given options.
Concept Introduction:
Element is a pure substance and it cannot be broken down into simpler pure substance by chemical means like
Elements that are laboratory synthesized are radioactive in nature and they convert back into the original naturally occurring element by emission of radiation. All the elements that occur naturally are not evenly distributed on earth and universe.
Radiations that are emitted from stars can be used to estimate the elemental composition of universe. This indicates that hydrogen and helium are mostly dominant. On Earth’s crust oxygen and silicon are the two elements that account for about
