If you mean the elements that are gases at standard temperature and pressure the the first four gases to be discovered are:
hydrogen (H) was discovered by Henry Cavendish in 1766;
nitrogen (N) was discovered by Daniel Rutherford in 1772;
oxygen (O) was discovered by Joseph Priestly in 1774; and
chlorine (Cl) was discovered by Carl Wilhelm Scheele in 1774.

How many different elements are used to make a molecule of methane?
A molecule of methane, CH4, is made up of one carbon atom and four hydrogen atoms, totaling five different elements in total.
Has electrolysis helped discover anything?
Yes, electrolysis has helped discover new elements, such as the isolation of sodium and potassium by Humphry Davy in the early 19th century. It is also commonly used in analytical chemistry to quantify the amount of a certain element in a compound.
Does the name of an element have to be approved by anyone?
For international standard, names are approved for and used by the International Union of Pure and Applied Chemistry. For each country, it is up to the head department in charge of similar aspects to decide (often through common and historic usage).
What elements make up talc?
There are four elements that are used to make talc. They are oxygen, hydrogen, silicon, and magnesium. Care should be used when using talc so that you do not inhale the dust from it.
Is hydrogen a reactent?
Yes, hydrogen is often used as a reactant in various chemical reactions, especially in processes like hydrogenation, combustion, and various industrial synthesis reactions. Its ability to easily react with other elements and compounds makes it a versatile reactant in chemistry.
What kind of radiactive elements are used in the field of chemistry?
These are the radioactive elements. See this link.
How is the Periodic Table used as a tool to study chemistry?
A periodic table is used to sort the 114 elements known to man. It is sorted in groups (alkalis, halogens, noble gases) and according to the number of electrons the elements have.
What is stoichimetry used for?
stoicheiometry is the division of chemistry that mainly deals with the relationships in combining elements.
Who first used the term element?
The term "element" was first used by the ancient Greek philosopher Empedocles in the 5th century BCE. He proposed that all matter is composed of four fundamental elements: earth, water, air, and fire. This concept influenced later philosophers and scientists, including Aristotle, who expanded on the idea by adding a fifth element, aether. The modern understanding of elements, particularly in chemistry, evolved much later with the development of the periodic table.
Where might you find a metalloid element used?
Metalloid, or semi metal is a term used in chemistry when classifying the chemical elements.

What grade level teaches the periodic table of the elements?
You should learn the Periodic Table whenever you take Chemistry in high school. Most people are a sophomore in high school when taking chemistry.
What are the properties and applications of multivalent elements in chemistry?
Multivalent elements in chemistry have the ability to form multiple positive oxidation states. This property allows them to participate in a wide range of chemical reactions and bond with different elements. Some common multivalent elements include iron, copper, and chromium. These elements are used in various applications such as in the production of steel, electronics, and pigments.
What are Inorganic elements of biological materials?
Inorganic elements of biological materials are components that are not naturally produced. This is often used to reference molecules in chemistry that are synthetic or man made.
What are the four elements that are commonly used in making jewelry?

What type of chemistry is determining the composition of a moon rock?
Analytical chemistry is the field involved in determining the composition of a moon rock. Techniques such as mass spectrometry and elemental analysis are often used to identify the elements and compounds present in the rock.
How does the four classical divisions of chemistry apply to everyday life?
The four classical divisions of chemistry are organic chemistry, inorganic chemistry, analytical chemistry, and physical chemistry. These divisions help us understand different aspects of the substances and reactions around us in everyday life, such as the composition of organic compounds in food, the properties of inorganic materials in household products, the analytical techniques used in testing water quality, and the principles of physical chemistry in cooking or brewing.
