Plz help I'm confused as to what the question means by substance. You have three elements, X, Y, and Z, with the following electronegativity values: X = 0.8 Y = 3.1 Z = 3.4 You react the elements to form the substances XY, XZ, and YZ. Answer the following questions: ● What kind of substance is XY? What kinds of bond is it? Explain your answer. ● What kind of substance is XZ? What kinds of bond is it? Explain your answer. ● What kind of substance is YZ? What kinds of bond is it? Explain your answer. ● For the ionic compounds, which element is the cation and which is the anion? Explain your answer.

For this question you have to remember the trend in electronegativity across a periodic table. Electronegativity in elements increases from left to right and upwards on the periodic table as in the picture provided. From this, you can tell elements with a low electronegativity are most likely metals right to the left of the periodic table, and elements with a relatively high electronegativity are most likely non-metals. From this information, you can probably try and work out what kind of bonding each pair has. For the cations and anions, remember that elements in group 1, 2 and 3 have positive charges, and elements in 5,6 and 7 have negative charges. So, elements more to the left will be more negative and elements more to the right will be more positive. I hope with this information you can work out what element will be more positive/negative. I hope this helps! :)

By the way, substance in this question is basically another way of saying a compound of different elements put together :)

I still don't quite understand how I'm suppose to answer the substance part of the question. Can you give me an example?

Ill help you with the first question. As we can see in the question, X = 0.8 in electronegativity As I said in my explanation before (and in the picture provided) electronegativity increases to the right and upwards on the periodic table. From this, we can tell that elements on the left side of the periodic table will be not as electronegative right? As they are completely on the left side, no where near the right (which is where flourine is, flourine is the most electronegative element) So, on the left side of the periodic table, there is group 1+2. In each of these groups are metals (alkali metals and alkali earth metals). So we can tell that X is most likely a metal element. Now for Y, it has an electronegativity of 3.1. This is high and would suggest it is on the right and upwards area of the periodic table. Elements on the right and top of the periodic table (not including noble gases, they aren't electronegative) are non-metals. This would leave us to suggest that Y is most likely a non metal. So X = metal, Y = non-metal, if these two elements make a compound, it would be ionic, as a non-metal + metal = ionic compound (meaning it has ionic bonding). Its an ionic substance as it is made from a metal and a non-metal. Does this make sense? :)
