Reduction is loss of oxygen. Oxidation is gain of oxygen. Can you balance this equation and then describe which is oxidation and which is reduction by creating and labeling your own arrows. ___Al(s) + ___Fe2O3(s) ___Al2O3(s) + ___ Fe(l) Please describe how this arrangement of playing cards relates to the periodic table of elements. Warning 5 part question! Check each diamond when complete ◊ Color code the following: Noble Gases, Non-Metals, Metalloids, Alkali Metals, Halogens, Alkaline-Earth Metals, and Transition Metals. ◊ Record the number of valence electrons in each period. ◊ Next to period 1, 2, 3, 4, 5, (make a sketch of the number of electron orbitals) ◊ Draw arrows showing the direction of increasing atomic number and atomic mass ◊ Show an arrow showing increasing electron negativity.
