Concept Introduction:
The compounds which contain ionic bond, which is a type of bond which formed between positive metal ion and negative, non-metal ions.
Answer to Problem 3.38P
The complete chart is as follows:
Explanation of Solution
Polyatomic ion is a group of covalently bonded nonmetal atoms which has an overall electrical charge.
In general, there are two types of ions: positive metal ions and negative non −metal ions.
When a neutral element gain electrons, the negative charge increases on it and it convert into negative ion. This negative ion is always greater than its parent atom.
Similarly, when a neutral element loss electrons, the negative charge decreases on it and it convert into positive ion. This positive ion is always smaller than its parent atom.
The general rules for writing formula of binary compound are as follows:
- To write the formula of positive ion first.
- The write the formula of negative ions after positive ion.
- Using criss-cross method, the charges of both the ions are interchanged.
- The formula shows the lowest whole-number ratio of both the ions.
For example: the symbols of the magnesium and chloride ions are as follows:
The formula of the ionic compound of these ions is as follows:
The complete chart is as follows:
The chart was completed using the criss-cross method, in which the respective ions are written with their formulas and charge and are then cross multiplied.
