Morphology
The phrase denotes a chemical element that belongs to a group associated with iron; this meaning is directly derivable from 'iron' (the metal/name of the element) + 'group' (a set or classification) + 'element' (a chemical substance). Classificatory noun phrases of this type are compositional and cross-linguistically common, so a B1 learner who knows the constituents should be able to understand the meaning.
Etymology
Iron group element comes from a simple idea: the word group shows these elements are a family around iron. Imagine iron as the family head and metals like cobalt and nickel as its relatives that act in similar ways, so the phrase means 'elements related to iron'.
