Question

What’s the symbol of the element Unnilquadium?

(a) Unl

(b) Unq

(c) Uns

(d) Ubn

The question was posed to me in a job interview.

Origin of the question is Periodic Table Classification topic in division Classification of Elements and Periodicity in Properties of Chemistry – Class 11

Answer 1

Correct choice is (b) Unq

For explanation I would say: Unnilquadium is a combination of un, nil, and quad i.e. 1, 0 and 4 as per IUPAC nomenclature. Its symbol is formed by joining the first letters. So combining u from uni, n from nil and q from quad, we get Unq.
