What are elements that exist in nature as uncombined atoms called?
Elements that exist in nature as uncombined atoms are called native elements. Some examples include gold, silver, copper, and graphite. These elements are typically found in their pure form due to their stability and inert nature.
Why do some elements form monatomic molecules?
Some elements form monatomic molecules because they have a stable electron configuration when they exist as single atoms. These elements have filled valence electron shells, making it energetically favorable for them to exist as single atoms rather than bonding with other atoms to form molecules.
Are molecules only found in compounds?
No, molecules can exist both in compounds and as individual elements. In compounds, molecules are formed when atoms chemically bond together. In the case of elements, some exist as diatomic molecules (like oxygen, O2), while others exist as single atoms (like helium, He).
Why do some elements exist as molecules in nature instead of as free atoms?
Most of the nonmetals (excluding the noble gases) exist as molecules because that is the lower energy state for them. The reaction of formation has a low enough actviation energy that it can occur spontaneously, and so it does.
Is it possible to get an element that is also a compound?
Yes because some elements exist in their natural state as diatomic molecules, and are thus both elements and molecules.See the Related Questions for a complete list of the diatomic molecules.
What are elements found in the nature as a diatomic molecule?
Some elements found as diatomic molecules in nature are hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), and chlorine (Cl2). These elements exist as diatomic molecules because they are more stable when paired together due to their electron configurations.
How do noble gases exist in nature?
Noble gases exist in nature in their elemental form because they are chemically inert and do not readily react with other elements to form compounds. They are typically found in the Earth's atmosphere and are extracted through processes like air separation. Additionally, noble gases can be found in some minerals and in small quantities in some natural gas deposits.
Are elements and compounds are made of atoms?
Yes. Elements are composed of individual atoms. Compounds are composed of molecules, which are chemical combinations of atoms. Some pure elements exist as molecules containing various numbers of combined atoms, such as atmospheric oxygen (O2) and ozone (O3).

No elements exist as molecules?
No. Several nonmetals form molecules. Here they are with the molecules they can exist as. Some of the rarer molecules are excluded Hydrogen (H2), Carbon (C60 and other fullerenes) Nitrogen (N2), Oxygen (O2, O3), Fluorine (F2), Phosphorus (P4), Sulfur (S8), Chlorine (Cl2), Selenium (Se8), Bromine (Br2), Iodine (I2)
What elements do not naturally occur as a diatomic molecules?
Some elements do not naturally occur as diatomic molecules, such as helium, neon, argon, krypton, and xenon. These elements exist as monatomic gases because they are stable in their single atom form due to having a full valence electron shell.
