Question

which of the following substances is an element

Answer 1

Answer:

An element is a substance that cannot be broken down into simpler components by any non-nuclear chemical reaction. An element is uniquely determined by the number of protons in the nuclei of its atoms.

Answer 2

An element's substance includes hydrogen, oxygen, iron, and gold.

Explanation:

• An element is the most basic type of stuff with its own set of attributes. Hydrogen, Oxygen, iron, and gold are examples of well-known elements (see the figure below).
• There is no way to break down elements into simpler substances.
• Similarly, one element cannot be chemically transformed into another.
• Any compound that cannot be broken into simpler components by standard chemical processes is referred to be a chemical element.
• All matter is made up of elements, which are the basic building blocks.
