Because the Hydrogen element only exists in nature by its self as a molecule with TWO hydrogen atoms. So if you have a sample of hydrogen, each hydrogen atom will be H2 (not just H). That is why it is called a Di-(two)-atomic-(atoms) molecule. Hope this helps.
The atoms that exist as diatomic molecules at room temperature and pressure are hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), bromine (Br2), and iodine (I2). These atoms bond with another atom of the same element to form stable diatomic molecules.
They share many properties, but one is that they all have 7 valence electrons.

The seven diatomic elements are hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine. Each of these elements exists as molecules composed of two atoms when they are not part of a compound.
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.

The 7 elements that readily form diatomic molecules are hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and Iodine. Astatine might theoretically form diatomic molecules, but it is so rare and radioactive that it is hard to study.
The atomicity of nitrogen is diatomic, meaning it exists as N2 molecules, which consist of two nitrogen atoms bonded together.
No, copper is a metallic element that exists as individual atoms in its natural state. It does not form diatomic molecules like elements found in group 17 of the periodic table (e.g., fluorine, chlorine).
They share many properties, but one is that they all have 7 valence electrons.
Two atoms are contained a single diatomic molecule. Elemental Hydrogen is an example of this where two hydrogen atoms share their only electrons in a single covalent bond.

Elements in group 7 are known as halogens and they all have 7 valence electrons in their outermost energy level. They are highly reactive nonmetals and tend to gain an electron to achieve a full outer shell, making them capable of forming ionic compounds. They also exist as diatomic molecules in their natural state.
The 7 diatomic elements are: hydrogen (H₂), nitrogen (N₂), oxygen (O₂), fluorine (F₂), chlorine (Cl₂), bromine (Br₂), and iodine (I₂). These elements naturally form molecules consisting of two atoms bonded together.
