Question

In the modern periodic table, the elements present in groups are called p-block elements.

• A. 12 to 17
• B. 1 to 7
• C. 13 to 18
• D. 9 to 14

Answer 1

The correct option is C 13 to 18

In the modern periodic table, the elements are classified into s, p, d and f blocks based on the subshell in which their last electron enters. From group 13 to 18, the last electron of the elements enter in their outermost p-subshell. Therefore, these elements are called p-block elements.
