Why do elements erbium, yttrium, ytterbium, terbium, have similar names?
by mistake in the elements naming approval process
from the name of the Swedish Ytterby mine
they are in the periodic table together therefore have similar names
from the surname of their discoverer, Ingmar Terber
Ytterby mine, located in the south-east part of the Swedish island and the town Resarö, was a rich source of many rare minerals. 4 chemical elements - yttrium, ytterbium, terbium and erbium - were named after the mine commemorating their origin.
