Concept explainers
Interpretation:
The way periodic table helps to calculate number of electrons lost by a metal is to be explained.
Concept introduction:
Ionic bonds are formed when there is complete transfer of electrons from one atom to another forming the bonds.
Answer to Problem 1RQ
Group number of metal gives this information.
Sodium belongs to group-I . So, it loses one electron to form ion in an ionic compound.
Magnesium belongs to group-II. So it loses two electrons to form ion in an ionic compound
Explanation of Solution
Periodic table helps to calculate number of electrons lost by a certain metal to form an ion in the ionic compound.
For example:
Group-I metals can loss one electron.
Group-II metals can loss two electrons.
Thus periodic table gives the information of number of electrons lost by metal.
