Interpretation:
Formula unit of magnesium bromide with the aid of Lewis symbols has to be drawn.
Concept Introduction:
G. N. Lewis formulated a method to represent valence electrons that participate in ionic bond formation. In Lewis symbols, each valence electron is depicted as dot and arranged around the symbol of the particular element. For example, in nitrogen the symbol is
For cationic elements, the dots equivalent to cationic charge are removed and then arranged around
For anions, the dots equivalent to anionic charge are added and then arranged around symbol of element.
When combined formula unit of an ionic compound is written numbers of atoms are written so that each metallic element gets accommodated by the non-metallic element.

- in the scope of the SCH4U course! please show all steps as im still learning how to format my answers in the format given, thank you!arrow_forwardhelp me solve this HWarrow_forwardMolecules of the form AH2 can exist in two potential geometries: linear or bent. Construct molecular orbital diagrams for linear and bent CH2. Identify the relevant point group, include all of the appropriate symmetry labels and pictures, and fill in the electrons. Which geometry would you predict to be more stable, and why? (Please draw out the diagram and explain)arrow_forward
