HELP PLEASE If an experiment produces 1.71 grams of X with a percent yield of 99.37%, what would the theoretical yield of X be in grams?
Report your answer to three decimal places (ignore significant figures).

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.

a electronegativity decreases beacuse the size of nucleus is bigger.
