Interpretation:
The atomic symbol and the classification of given elements as metals, non metals and metalloids is to be predicted.
Concept introduction: Elements are classified into metals, nonmetals and metalloids on the basis ease by which they can gain or lose electrons.
The elements which can easily lose their valence electrons are known metals.
The elements which have high
The elements which have intermediate properties between metals and non metals are known as metalloid
To determine: The atomic symbol and the classification of given elements as metals, non metals and metalloids.
