Question

Define element, and give an example of an element.

Answer 1

An element is a pure substance that cannot be broken down into simpler substances by chemical means. Each element consists of atoms that have the same number of protons in their nuclei, which is known as the atomic number. Elements are the fundamental building blocks of all matter and can exist as solids, liquids, or gases at room temperature.

An example of an element is carbon (C), which has an atomic number of 6, meaning it has 6 protons in its nucleus. Carbon is a key element in organic chemistry and is essential for life, as it is a primary component of biological molecules such as carbohydrates, proteins, and nucleic acids.
