8. jautājums.
Vislielākā atšķirība starp masas daļu un daudzumdaļu % ir nemetāliem – skābeklim, silīcijam un ūdeņradim.

Ūdeņradis = 14,5%
Silīcijs = 9,5%
Skābeklis = 5,7%

Atšķirība, iespējams ir tāpēc, ka šie nemetāli ir ļoti vajadzīgi dabai. Piemēram, bez skābekļa pasaule iztikt nevarētu, tāpat kā bez ūdeņraža.
