Key Concepts
These are the key concepts you need to understand to accurately answer the question.
Group VA elements
Group VA, also known as Group 15, includes the elements nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi). These elements belong to the p-block of the periodic table.
They are not transition metals. Instead, they are a mix of nonmetals, metalloids, and metals.
Transition metals are found in the d-block between Groups 3 and 12. Thus, it is incorrect to classify Group VA elements as transition elements.

Transition elements
Transition elements are located in the d-block of the periodic table, spanning Groups 3 to 12. These elements are characterized by their ability to form multiple oxidation states and colored compounds.
All transition elements are metals, known for their conductive and malleable properties.
Common examples include iron (Fe), copper (Cu), and gold (Au).
Transition metals often form complex ions and have significant roles in industrial processes, catalysis, and biological systems.

Group I and II elements
Group I elements, also referred to as alkali metals, include lithium (Li), sodium (Na), and potassium (K). These metals are highly reactive, especially with water, and are known for forming strong bases (alkalies).
Group II elements, also called alkaline earth metals, consist of beryllium (Be), magnesium (Mg), and calcium (Ca). They are less reactive than alkali metals but still quite reactive.
Both these groups fall under the category of 'normal' or main group elements, distinguished from transition elements.

Noble gases
Noble gases make up Group 18 (formerly called Group 0) and include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
These elements are characterized by their extremely low reactivity, owing to their complete valence electron shells. They exist as monoatomic gases under standard conditions.
Noble gases are used in various applications, such as lighting (neon lights), inert atmospheres for welding (argon), and cooling (liquid helium). Their inert nature also makes them important in preventing unwanted chemical reactions.
