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.
Oxygen occurs naturally as a diatomic molecule with a double covalent bond. Each oxygen atom shares two electrons to form the O2 molecule, creating a stable arrangement with a full set of valence electrons.
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.
There are 92 naturally occurring elements on Earth.
92 elements occur naturally on the periodic table.
:O:=:O:Standard form of oxygen. It's elemental and gaseous form. O2
Which of the following does not occur naturally as a diatomic molecule? Chlorine, Hyrdogen, nitrogen or sulfur?
There are seven elements that occur naturally as diatomic molecules: hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), bromine (Br2), and iodine (I2).

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.
Hydrogen is formed as molecule containing two atoms, just as nitrogen, and oxygen.

how may elements occur naturally in nature
Not all the elements occur naturally; some elements are man-made.
There are 92 naturally occurring elements on Earth.
There are only two elements, nitrogen and oxygen, that occur in any quantity as simple substances in diatomic gas form. The mixing ratio of dihydrogen gas in the lower atmosphere is around 500 parts per billion, so that would make three if we are really scratching around.

Elements 1-92 except 43 (technetium) and 61 (promethium) occur naturally. So, there are 90 naturally occurring elements.
