To predict the formula of the compound formed between element X from Group 13 and element Y from Group 16, we can follow these steps: ### Step 1: Identify the Valencies - **Element X (Group 13)**: Elements in Group 13 have 3 valence electrons. Therefore, the valency of element X is +3. - **Element Y (Group 16)**: Elements in Group 16 have 6 valence electrons. To find the valency, we can use the formula: \[ \text{Valency} = 8 - \text{number of valence electrons} \] ...
