Correct. There are four electron domains around the central atom X, and their geometry is tetrahedral, which minimizes the repulsion between the four electron pairs. The Z-X-Z bond angle is approximately 109.5°, and the molecular geometry is bent. A particle-level diagram of a metallic element is shown above.
Jun 12, 2019 · Helen S. asked • 06/12/19 I am giving a medical order of 14mEq of Potassium Chloride that is to be added to 1L bag of fluids. The Kc1 solution strength is 20 m Eq/10mL. Step 3: Part 2.
