Question

Which is not a prime element?

• A. Carbon
• B. Nitrogen
• C. Hydrogen
• D. An element that can be factored into non-unit factors

Hint:

In chemistry, prime elements are those that exist in their simplest form and cannot be decomposed into smaller, fundamental elements.

Answer 1

The Correct Option is D

A prime element is one that is fundamental and cannot be broken down further into simpler units. Elements like carbon, hydrogen, and nitrogen are considered prime elements because they are basic and cannot be decomposed. The option (d) refers to something that can be factored, which disqualifies it from being a prime element.
