(a) Interpretation: Identify the given elements as metals and non-metals with their position in the periodic table. Concept Introduction: In the periodic table as we move across the period from left to right the metallic nature of element decreases. Therefore the left most side of periodic table contains metallic elements whereas right most side contains non-metals.

Definition Definition Number of protons in the nucleus of an atom. It uniquely identifies an element, as the number of protons determines the element's properties. The periodic table of elements is arranged based on increasing atomic numbers, allowing scientists to easily locate and study elements.

Interpretation Introduction
(a)
Interpretation:
Identify the given elements as metals and non-metals with their position in the periodic table.
Concept Introduction:
In the periodic table as we move across the period from left to right the metallic nature of element decreases. Therefore the left most side of periodic table contains metallic elements whereas right most side contains non-metals.
Interpretation Introduction
(b)
Interpretation:
Identify the given elements as metals and non-metals with their position in the periodic table.
Concept Introduction:
In the periodic table as we move across the period from left to right the metallic nature of element decreases. Therefore, the left most side of periodic table contains metallic elements whereas right most side contains non-metals.
Interpretation Introduction
(c)
Interpretation:
Identify the given elements as metals and non-metals with their position in the periodic table.
Concept Introduction:
In the periodic table as we move across the period from left to right the metallic nature of element decreases. Therefore, the left most side of periodic table contains metallic elements whereas right most side contains non-metals.
Interpretation Introduction
(d)
Interpretation:
Identify the given elements as metals and non-metals with their position in the periodic table.
Concept Introduction:
In the periodic table as we move across the period from left to right the metallic nature of element decreases. Therefore, the left most side of periodic table contains metallic elements whereas right most side contains non-metals.
