Many elements do not exist as diatomic molecules. Metals, like iron, copper, silver, lead, etc. Even some nonmetals, helium, argon, sulfur, etc. Only a few do exist as diatomic molecules, hydrogen, oxygen, nitrogen, chlorine, fluorine, bromine, and maybe astatine.
Elements 1-92 except 43 (technetium) and 61 (promethium) occur naturally. So, there are 90 naturally occurring elements.
With the conditions of temperature and pressure found on the Earth hydrogen and oxygen in their free state are gas molecules consisting of two atoms. But nitrogen gas can also be found in this form.
Both nitrogen and oxygen are nonmetal elements that commonly occur as diatomic gasses. That is, they form molecules consisting of two atoms each. Both are also highly electronegative.
The seven diatomic molecules are hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), bromine (Br2), and iodine (I2). These molecules naturally occur as two atoms bonded together.
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.
Bromine, Iodine, Nitrogen, Chlorine, Hydrogen, Oxygen, FluorineRemember: BrINClHOF (sounds like Brinklehoff)There are 7 elements that occur in nature as diatomic molecules. They are hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine. In equations for chemical reactions, they must be expressed as H2, N2, O2, F2, Cl2, Br2, and I2.

All elements can exist as individual atoms in excited states. However, at standard temperature and pressure, hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine exists as diatomic molecules.
Which of the following does not occur naturally as a diatomic molecule? Chlorine, Hyrdogen, nitrogen or sulfur?
No. Air always contains two elements, oxygen and nitrogen, neither of which is a compound, although they occur as diatomic molecules.
how may elements occur naturally in nature
Two nonmetals that occur in the free state are oxygen and nitrogen. These elements are abundant in the Earth's atmosphere and exist as diatomic molecules (O2 and N2).
Many elements do not exist as diatomic molecules. Metals, like iron, copper, silver, lead, etc. Even some nonmetals, helium, argon, sulfur, etc. Only a few do exist as diatomic molecules, hydrogen, oxygen, nitrogen, chlorine, fluorine, bromine, and maybe astatine.
No elements can be made from molecules, because molecules are made from elements instead. If the question is really, "What elements normally occur in nature as diatomic molecules?", the answer is hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine.
There are 92 naturally occurring elements on Earth.
Not all the elements occur naturally; some elements are man-made.
