(5 pts.) 1A) Based on the accompanying electronegativity data, calculate the percent ionic character in mercury selenide (HgSe), and determine whether the bonding in HgSe is ionic, covalent, metallic, hydrogen, or van der Waals (4 pts.) B) Based on your answer to part A), find the appropriate radii and charges. A sufficient partial table of radii and charges is part of your coursepack. Radius for selenium in mercury selenide Radius for mercury in mercury selenide= Selenium charge = Mercury charge = (2 pts.) C) What is the electron configuration of Hg in HgSe? = = (2 pts.) D) What is the electron configuration of Se in HgSe (mercury selenide)? (4 pts.) E) Based on your answer to part B) and using the supplemental flowchart, determine the coordination number for both Hg and Se in mercury selenide. (8 pts.) F) Based on your answer to part E), sketch the crystal structure for HgSe. Remember, the definition of a lattice parameter is how far you have to go atom or ion. Do not switch between crystal systems for the rest of the along a direction that the atoms or ions touch until you reach an equivalent problem. You will be graded partly on how consistent you are. You can refer to figures on the formula sheet if the unit cell is too difficult to draw.
