Quizplus · Accepted Answer

None of these compounds exist in reality, but the format is similar to that of binary compounds formed between nonmetals and metalloids. The first element is named by its elemental name and the second is named by using the suffix -ide. The numbers and letters following each element likely indicate the number of atoms of each that make up the compound. However, the element with the symbol "U1" does not exist, so this compound cannot exist.
