1) The question screenshot as been attached down below answer question 4 d step-by-step.

Why is the ability to draw a Lewis structure considered a core chemistry skill?

♥ Draw Lewis structures for each of the following. Use the DEN and the number of REDs around thecentral atom to select the type of bonds, the molecular shape, and type of molecule from the lists.♥ Do not put covalent bonds between metals and nonmetals♥ Put brackets around anions to show both charge and quantity.

Draw a Lewis structure for SiH4 BrF3 H2CO please show evidence that you are using all 5 steps in the process for drawing Lewis structure.

= O ELECTRONIC STRUCTURE AND CHEMICAL BONDING Predicting deviations from ideal bond angles = (co-) anion. Consider the carbonate What is the central atom? Enter its chemical symbol. How many lone pairs are around the central atom? What is the ideal angle between the carbon-oxygen bonds? Compared to the ideal angle, you would expect the actual angle between the carbon-oxygen bonds to be... 0 7 (choose one) X 5 3/5
