What different elements are found in baryte?

A. $Ca, S, O$

B. $Zn, S, O$

C. $Ba, S, O$

D. $Mg, S, H, O$

Correct Option is (C)

Baryte, a mineral composed of barium sulfate $({BaSO}_{4})$ , falls under the study of s-block elements because barium is an s-block element. This chapter would typically cover the properties, compounds, and uses of s-block elements, including barium, and how they form various compounds like barium sulfate.

Which of the following is NOT true for alkaline earth metals?

A. Their divalent ions have inert gas configuration.

B. They are more electropositive than alkali metals

C. Alkaline earth metals are silvery white and soft.

D. Their compounds are diamagnetic and colourless.

Correct Option is (B)

For the alkaline earth metals :

Option A is true. When alkaline earth metals lose their two outermost electrons to form divalent ions, they attain an inert gas configuration.

Option B is NOT true. Alkali metals are more electropositive than alkaline earth metals.

Option C is true. Alkaline earth metals are generally silvery-white and somewhat soft (though harder than alkali metals).

Option D is true. Compounds of alkaline earth metals are usually colorless and diamagnetic due to the absence of unpaired electrons.

So, the correct answer to the question is :

Option B : They are more electropositive than alkali metals.
