Morphology
The phrase is compositionally understandable — a learner who knows 'helium' (an element) and 'group' (a set or collection) can infer it refers to a set that includes helium. However, recognizing that this specifically denotes the class of noble/inert gases and the conventional chemical term requires domain knowledge and the construction is not a fully predictable everyday phrase, so it is only partially transparent to B1 learners.
Etymology
Helium group comes from naming a set of similar gases after helium, the first of them noticed by scientists. Helium was even seen in the Sun before it was found on Earth. These gases hardly join with other elements; they 'do not react', so helium group means the set of unreactive gases on the periodic table.
