Skeiðbundna skipanin

**Skeiðbundna skipanin** (á enskum: the periodic table) er ein skipan við øllum frumevnunum sett upp í bólkar og periodur, sett upp í teigar. Hvør av teigunum umboðar eitt frumevni, og hvør perioda umboðar tal av skølum. Frumevni í sama bólki hava somu elektronsamanseting í uttasta skali og hava tí ofta eins evnafrøðiligar eginleikar. Frumevnini eru sett upp í rað eftir atomnummari, t.v.s. hvussu nógvar protonir eru í kjarnanum á atominum. T.d. hevur jarn (Fe) atomnummar 26 og eru sostatt 26 protonir í kjarnanum.
