Two main-group elements are highlighted in the outline of the Periodic Table below: X Y What can you say about these elements without knowing exactly which they are? Use that knowledge to answer the questions in the following table, if possible. Important: do not try to figure out exactly which elements are marked, and then use your knowledge of the properties of each specific element. You don't need to. You will also be marked wrong for any answer, correct or not, that can't be determined from the rough location of each marked element in the Periodic Table. The atoms of which element are more likely to be the cations in an ionic compound? O Element X O Element Y O Can't say without more information. X

What is NOT true about molecular compounds? Select the correct answer below: They are also called covalent compounds. O They are typically formed between nonmetals. They result when atoms transfer electrons to form ions. O They typically exist as gases, low-boiling liquids, and low-melting solids.
