I think the correct answer from the choices listed above is the third option. <span>In the redox reaction given, the element that was reduced was Fe or iron. It's charge reduced from +3 to zero, a neutral charge. Hope this answers the question. Have a nice day.</span>
I will state the electronegativities of each element.
Ca = 1.00
F = 3.98
H = 2.20
P = 2.19
Na = 0.93
The highest electronegative element is F (Fluorine).
Solubility because when you have to test for it you need to add another liquid to the pure substance and that may cause a chemical change
The correct answer is elements in family 7 have similar properties because elements in the same group or family have the same number of valence electrons.
