Write a balanced equation for the double-replacement precipitation reaction described, using the smallest possible integer coefficients. a precipitate forms when aqueous solutions of chromium(iii) iodide and potassium hydroxide are combined.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

that tool would be a compass
