According to Newland’s Law of Octaves, every eighth element has properties similar to those of the first element. Which of the following elements has properties similar to those of N?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. P.
According to Newland’s Law of Octaves, every eighth element in the periodic table has properties similar to the first element. Nitrogen (N), being the 7th element, is followed by phosphorus (P) as the 15th element, which is exactly eight positions ahead. Therefore, phosphorus exhibits properties similar to nitrogen, such as forming compounds with a valency of three and sharing similar chemical behavior. This pattern reflects the periodicity in elemental properties. Elements like boron (B), aluminum (Al), and sulfur (S) do not follow this rule in relation to nitrogen, making phosphorus the correct element with similar properties to nitrogen under this law.
