What properties do you expect it to have?Elements in the same group in the periodic table (a) have similar chemical properties. (b) are called isotopes. (c) have consecutive atomic numbers. (d) make up a period of elements.What are the e...
They usually depend on the radioactive decay of different isotopes of elements, and can be used on objects that are hundreds to billions of years old. For an in-depth explanation, see "Accuracy of Fossils and Dating Methods." The evidence for evolution of life is overwhelming and conclusive...
>Avogadro’s number is big enough to be considered the physicists’ true infinity.I think that the notion of infinity in mathematics is quite different from "very big". If you add one mole of oxygen to one mole oxygen, the you get two mole oxygen. This is definitely more, than one mol...
then survived Earth's tumultuous geologic history for more than four billion years. The age of the crystals was confirmed using dating techniques that measure the proportion of radioactive and radiogenic isotopes (parent and daughter isotopes
