The noble gases.
Alkali metals are not found as pure elements in nature.
Elements found on the periodic table can be found in nature in various forms such as minerals, rocks, and gases. Elements like oxygen, carbon, and gold are naturally occurring and can be found in soil, water, and the atmosphere. Many plants and animals also contain elements from the periodic table in their biological structures.
All the elements with the atomic number in the range 1-97.
Pure elements are found least in nature compared to compounds and mixtures. Most elements exist bonded to other elements to form compounds or mixed with other substances to form mixtures in nature. Pure elements are less common due to their tendency to react and combine with other elements.
Many elements are found in nature in molecular form - two or more atoms (of the same type of element) are bonded together. Oxygen, for example, is most commonly found in its molecular form "O2" (two oxygen atoms chemically bonded together).
The noble gases.
Elements found in nature are referred to natural elements, as opposed to synthetic, which are man made.
The chemical substances found in the atmosphere exist as gases.
Most elements in nature are found in the solid state.
All the elements before neptunium are found in the nature. Also neptunium can be found in the nature only in ultratraces resulting from nuclear weapons experiments or other experiments.

In the nature the majority of chemical elements are found as compounds.
Chemical elements doesn't contain proteins.
There are currently 118 elements, ranging from #1 Hydrogen to #118 Ununoctium. Many of the transuranium elements (#93-#118) are synthetic, meaning that the only place they have been found is in a laboratory, thus do not exist in nature. Technetium (#43) and Promethium (#61) are also synthetic.
