Question

Identify the correct statement.

• A. All s block elements are metals
• B. All p block elements are metals
• C. All s block elements are non-metals
• D. All p block elements are non-metals

Answer 1

The Correct Option is A

The question asks us to identify the correct statement regarding the periodic table blocks. The options are related to the characteristics of elements within the s and p blocks.

Understanding the s Block: The s block of the periodic table consists of two groups: Group 1 (alkali metals) and Group 2 (alkaline earth metals). These elements have their outermost electrons in the s subshell. A key feature of these elements is that they are all metals. Typical properties of metals include high electrical and thermal conductivity, malleability, ductility, and a lustrous appearance. Given these properties, the statement that "all s block elements are metals" is indeed correct.

Understanding the p Block: The p block includes Groups 13 to 18 on the periodic table. This block is distinctive because it contains a mix of metals, non-metals, and metalloids. Therefore, not all p-block elements are metals, nor are they all non-metals. This variability in composition makes the remaining options incorrect.

Conclusion: Based on these explanations, the only correct statement is that "all s block elements are metals."

Answer 2

Correct answer: All s block elements are metals
 
Explanation:
The periodic table is divided into blocks (s, p, d, f) depending on which atomic orbital is being filled with electrons.

• The s-block elements include Group 1 (alkali metals) and Group 2 (alkaline earth metals). These elements are all metals and are known for being highly reactive, especially the Group 1 elements.

• The p-block elements include Groups 13 to 18. This block contains a mix of metals, non-metals, and metalloids. So, it is not correct to say that all p-block elements are either metals or non-metals.

Therefore, the correct statement is that all s-block elements are metals.
