(a)
Interpretation:
The given elements have to be identified as metals, metalloids or non metals.
Concept introduction:
Metals: It is an element which has the following properties: solids at room temperature except mercury, hard in solid state, good conductors of both heat and electricity, ductility, high density, malleability, high melting and boiling point, tendency to form basic oxides by reacting with oxygen, tendency to form positive ion when they looses the electron and get shiny by polishing.
Nonmetals: It is an element or substance but not metal, they have the following properties: they may exist as solid, liquid or gas at room temperature, easily breakable, bad conductors of both heat and electricity, melting and boiling points are low, when they react with oxygen they will form acidic oxides, tendency to form negative ions when they loses electron except hydrogen, which forms positive ion, compared to metals, nonmetals will look dull in nature.
Metalloids: It is a chemical element has the properties of both metals and nonmetals.
To identify: The given element as a metal or nonmetal or metalloid.
