Concept explainers
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.
