Question

Can someone explain to me how to do this!
1. 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 an

Answer 1

This should help,

Note the scale they used to generate this diagram might be different than the scale they used in your question, electronegativity is value that is hard to exactly quantify based on my knowledge of it.

Answer 2

So in that periodic table the most electronegative elements are red and the least electronegative elements are purple

Answer 3

Oh oh okay... I'm looking over it right now!

Answer 4

Thank you!

Answer 5

typically when Group 1A and Group 2A elements interact with Group 5A, 6A and 7A elements you get ionic bonds forming

Answer 6

Since 5A, 6A and 7A are very electronegative they want electrons to be more like the noble gas they are closest to (have a full octet), whereas Group 1A and Group 2A will give up electrons for the same reason

Answer 7

There are trends in the periodic table that are important to recognize because they can describe reactivity of various elements.

Group 4A elements are interesting because they can go both ways, Group 3A will more often than not give up electrons but it can form covalent bonds so yeah.

Answer 8

Group 3A, 4A, 5A, 6A and 7A form covalent bonds with each other, so they share electrons, although don't think this sharing is equal because it isn't a more electronegative element will hog electrons in a covalent bond resulting in a partial polarization of the molecules charge (this is important if you get into intermolecular bonds).

Answer 9

I hope you know what I mean when I speak of groups, they are just the different columns of the periodic table, for example group 7A is the halogens, group 8A is the noble gases etc

Answer 10

If you need clarification on anything inform me and I will try to help

Answer 11

Thank you so much! I think I somewhat understand now. It might take me awhile to go over all that you wrote but I really appreciate it!

Answer 12

Note that hydrogen is an exception in group 1A, it forms covalent bonds with Group 3A-7A elements, it can also form ionic bonds with group 1A and 2A elements.

Answer 13

It is just a proton which makes sense by it high electronegativity relative to other group 1A members
