Interpretation:
The formation of ions is to be determined.
Concept Introduction :
Every atom tends to be stable by completing its octet. The atom completes its octet by losing or gaining electrons.
Answer to Problem 19LC
Ions are formed when an atom gains or loses one or more electrons.
Explanation of Solution
An ion is formed by gaining or losing electrons by an atom. The number of electrons lost or gained by an atom becomes its charge. If an element loses electrons, it has a positive charge. In the symbol for an ion, the charge is represented as a superscript of the symbol of the atom for that element.
Consider an example,
Sulfur is a non-metal; thus, it gains electrons to form a sulfur ion. Here, sulfur belongs to group 16 thus, it has 6 valance electrons. It can gain 2 electrons to complete its octet or to attain noble gas configuration. Thus, the formula of ion will be
