Identify whether the given statements about p-block elements are correct or incorrect.
Statement A: In p-block elements, the last electron enters the outermost p orbital.
Statement B: The non-metals and metalloids exist only in the p-block of the periodic table.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. Both Statements A and B are correct.
Statement A: Correct. Within p-block elements, the outermost electron is added to the outermost p orbital. This occurs because p-block elements position their valence electrons within the p orbital of the highest principal quantum number.
Statement B: Correct. The p-block of the modern periodic table contains three distinct types of elements: metals, non-metals, and metalloids, all coexisting within this section.
