This questions was previously asked in

SSC MTS 14th October 2021 Shift-1

Beryllium

Magnesium

Potassium

Calcium

Correct Answer: 3. Potassium

Explanation:

Newlands’ Law of Octaves (1865) states that every eighth element has properties similar to the first when arranged by increasing atomic mass.

In this pattern:

Sodium (Na) is the first element in a set.

Counting eight elements from Sodium gives us Potassium (K).

This is similar to the way musical octaves repeat every eighth note.
