You are already equipped that has a sample of food stuff. How will you perform checks for that presence of starch and proteins in it?
Remedy: Dobereiner arranged specified components with comparable Attributes in groups of 3 in this type of way which the atomic mass of the middle factor was almost the same as the standard atomic masses of the main and 3rd ICSE Class 11 Physics elements.
Answer: The elements of Group I have only one electron inside their respective valence shells and therefore have a strong tendency to lose this electron. The tendency to lose electrons consequently, depends upon the ionization enthalpy. Because the ionization enthalpy decreases down the group therefore, the reactivity of team one things boosts in a similar purchase Li < Na < K < Rb < Cs.
