Newland's law of octaves states that

Options

A. Every eighth element had properties similar to the first element
B. Every third element had properties similar to the first element
C. The properties of the middle element were in between the other two members
D. The properties of the elements were repeated after regular intervals of 3,4 or 8 elements.

Answer

**Step-by-Step Solution:**

1. **Understanding Newland's Law of Octaves**: Newland's Law of Octaves is a principle in chemistry that was proposed by John Newlands in 1865. It relates to the arrangement of elements in the periodic table.

2. **Arrangement of Elements**: According to this law, elements are arranged in increasing order of their atomic weights. This means that as you move from one element to the next in the periodic table, you are moving to an element with a higher atomic weight.

3. **Repetition of Properties**: Newland observed that every eighth element has properties similar to the first element. This means that if you take any element, the element that is eight places down in the arrangement will exhibit similar chemical properties.

4. **Conclusion**: Therefore, the correct statement regarding Newland's Law of Octaves is that every eighth element has properties similar to the first element. This is the essence of the law, highlighting the periodic nature of the elements based on their atomic weights.

**Final Answer**: Newland's Law of Octaves states that every eighth element has properties similar to the first element when arranged in order of increasing atomic weights.
