Assertion: Group 15 elements exhibit similar chemical properties due to the presence of five valence electrons.
Reason: The valence shell of Group 15 elements contains five electrons, which is one less than the stable octet configuration.
Both assertion and reason are true, and the reason is the correct explanation of the assertion.
Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
The assertion is true, but the reason is false.
The assertion is false, but the reason is true.
Answers (1)
Group 15 elements (nitrogen, phosphorus, arsenic, antimony, and bismuth) all have five valence electrons in their outermost shell, which leads to similarities in their chemical behavior. The Reason provided also explains why they have similar properties, as the tendency to gain an additional electron to achieve a stable octet configuration makes them behave similarly in chemical reactions. Both Assertion and Reason are correct, and the Reason is the correct explanation for the Assertion. Hence option A is the correct answer.
Option(2) Both assertion and reason are true and the reason explains assertion correctly. Hence option 2 is incorrect.
Option(3) Both assertion and reason are true. Hence option 3 is incorrect.
Option(4) Both assertion and reason are true. Hence option 4 is incorrect.
