Question

Find the pair of elements having similar properties by applying Newlands law of Octaves (Example: Mg & Ca): Set 1: F, Mg, C, O, B Set II: Al, Si, S, CI, Ca​

Answer 1

Answer:

F & Cl

C & Si

O & S

B & Al

Explanation:

According to Newlands' law of octaves when the elements are arranged in order of increasing atomic weights, then every element will have similar properties to the one eight places after it.

So in the example given: Mg's atomic mass is 24 and Ca is 40: 24+8+8=40.

The properties of magnesium and calcium are similar.
