<span>Dmitri Mendeleev's Periodic Law states that chemical and physical properties repeat themselves in groups of 8.</span>
Answer:
Oh, you need to get the blue dots, and move them to the table or graph to plot them!
Hope that makes sense!
Answer:
a. 63.2%
b. 11.7%
c. 73.3%
d. 0.995%
e. 55.5%
Explanation:
An ionic compound is a compound that is formed by ions, so one of the elements must donate electrons (which is the cation, the positive ion), and the other will receive these electrons (which is the anion, the negative ion).
The power of an element has to attract the electrons is called electronegativity, and so, as higher is the difference of electronegative of the elements, it is more probable that one of them will "still" the electrons and will form an ionic compound. The percent of this ionic character can be found by the Pauling's equation:
*100%
Where
is the electronegativity difference of the elements. Thus, consulting an electronegativity table:
a.
= 1.5
= 3.5
*100%
%IC = 63.2%
b.
= 1.6
= 2.1
*100%
%IC = 11.7%
c.
= 0.7
= 3.0
*100%
%IC = 73.3%
d.
= 1.7
= 1.9
*100%
%IC = 0.995 %
e.
= 1.2
= 3.0
*100%
%IC = 55.5%

I don't really know what that is so here is a picture of it
