How many times bigger is the earth than a nucleus?

Almost all of the mass (more than 99%) of an atom is contained in the dense nucleus. An atomic nucleus is much, much smaller than an atom. The cloud of electrons that "orbit" the nucleus and define the "size" of an atom is roughly100,000 times as large as that atom's nucleus!

Ifound this on google “laws of chemical combination. it states that matter can neither be created nor destroyed. it stated that a given compound always contains exactly the same proportion of elements by weight.” i hope this you for what your looking for.
