Answer 2

In chemistry, an element is defined as "any pure substance made completely of one type of atom that cannot be broken by chemical processes."

Explanation:

• It has a fixed number of protons, and changing the amount of protons in an element completely changes the element's type. The atomic number is the number of protons in the nuclei that is unique to each element. To date, 118 elements have been identified.
• Humans were already aware of elements such as carbon, sulphur, iron, tin, lead, copper, mercury, silver, and gold. These elements were used to create weapons, shelter, fuel, and other items.
• Elements including arsenic, antimony, bismuth, and zinc were gradually discovered. Approximately 65 additional elements were found over the next 200 years. These comprised elements such as oxygen, silicon, iodine, calcium, magnesium, and others.
