Answer:
C. They can be bonded together to create different substances.
Step-by-step explanation:
Elements are the simplest substances that can get without losing their properties. They can be found on the periodic table.
To help answer this question we can break down each answer choice.
Choice A
Answer A cannot be correct simply because of the definition of an element. A substance of a pure element cannot be broken down into any simpler substance. The only thing beyond an element is subatomic particles like protons and electrons, which are not considered substances. So elements are the simplest substances that exist.
Choice B
Many elements are found in nature. It would be impossible to live if elements were not naturally occurring. For example, oxygen is an element. Oxygen is found naturally in the atmosphere and is replenished by photosynthesis and the carbon cycle. Additionally, all life is carbon-based, so of course, carbon is also naturally occurring.
Choice C
Chemical compounds and substances surround us every day. Just as we need oxygen to breathe, carbon dioxide is also an important part of life. Carbon dioxide is a substance created by the bonding of carbon and two oxygen atoms when we breathe out. So, it is true that elements can be boned to create substances.
Choice D
As stated in the explanation for choice B, elements can be found naturally. There are some elements created in a lab like Technetium, but others such as sulfur and oxygen are not created in labs.
