Sulphur
The standard heat of formation of a free element in its standard state is defined as zero. This is because it is the reference point from which the heat of formation of other compounds is determined.
There are many nonmetals that are rarely found in their elemental form naturally. One of the more widespread of these is chlorine. Because chlorine is so reactive, it is almost always present as compounds, such as sodium chloride.
Neon is found in its free state in trace amounts in the Earth's atmosphere, making up about 0.0018% of the atmosphere.
Argon is found in the Earth's atmosphere, where it exists as a free element. It is also commonly found in combination with other elements in minerals such as feldspar, micas, and zeolites.
Yes. copper is one of the elements that may, with luck, be found in the native state.
carbon
Sodium, being a reactive element In group 1, cannot be found as element in nature. One of its common compounds is rock salt.
most elements have partly filled orbitals (or shells) and they try to gain, lose or share electrons so as to satisfy octet rule. Hence they are reactive and not generally found in free state
Sodium (Na) is a highly reactive element so it cannot be found in free state but we can have it in compound form like NaCl.
nitrogen
Maine was admitted as a free state

nitrogen
Yes! Boron is the only non-metallic element in Group 13 of the periodic table and is essential for the growth of plants. It's also used in various industrial applications, such as in the production of fiberglass and borosilicate glass.
The themes found in the novel In A Free State by V.S. Naipaul are racism and the main theme freedom.
