Question

In the modern periodic table group 2 (IIA) elements are called as

• A. Alkali metals
• B. Alkaline earth metals
• C. Halogens
• D. Noble gases

Answer 1

The Correct Option is B

To solve this problem, we need to identify the elements of group 2 (IIA) in the modern periodic table.

1. Group 2 (IIA) Elements:
In the modern periodic table, the elements in group 2 are known as alkaline earth metals. These elements include beryllium (Be), magnesium (Mg), calcium (Ca), and others. They are characterized by having two electrons in their outermost shell and typically exhibit basic (alkaline) properties when reacting with water.

2. Evaluating the Options:
(1) Alkali metals – Incorrect (Alkali metals are in group 1, not group 2.)
(2) Alkaline earth metals – Correct ✅ (Group 2 elements are called alkaline earth metals.)
(3) Halogens – Incorrect (Halogens are in group 17.)
(4) Noble gases – Incorrect (Noble gases are in group 18.)

Final Answer:
The correct option is (B) Alkaline earth metals.
