Very few elements exist in their free state in nature. The vast majority of them exist as compounds, chemically bonded to other elements.
These elements exist as compounds.
Yes, The elements hydrogen, nitrogen, oxygen, and sulfur are all molecular elements that exist in nature. Due to their reactivity, it is rare to find the halogens and phosphorus in their elemental forms in nature.
Radioactive elements exist in all groups of the periodic table.
Mendeleev was the first to notice that properties of elements exist as a perdoic function of atomic mass
These elements exist also naturally - in infinitesimal amounts - in the Earth crust.But practically are artificial elements.
If no elements existed, nothing would exist.
Very few elements exist in their free state in nature. The vast majority of them exist as compounds, chemically bonded to other elements.
94 natural elements and 14 artificial elements
Francium is the rarest metal. It is estimated that only 30 grams of it exist in earth's crust. However, most of the artificially created elements on the periodic table near the end are equally rare because they only exist for extremely small amounts of time and so they do not exist anywhere in the universe currently.
These elements exist as compounds.

Lower levels of the atmosphere.
All elements and all compounds do not exist as molecules. As examples, noble gases exist as individulal atoms and ionic compounds form lattices.
88 different elements exist in nature.
Elements can either be synthetic or natural. Synthetic elements are made artificially in laboratories, while natural elements exist in their natural state in nature. Natural elements can further be defined as native elements. These elements exist in their uncombined state.
