Nitrogen, Oxgen and all the halogens (Fluorine, Chlorine, Bromine, Iodine and Astatine) exist as a diatomic molcules.
You might be thinking of Oxygen, which is capable of bonding with itself to make O2. If, however, you mean two different atoms, you are mistaken. An element only has one type of atom; that's the whole very nature of an element. They're the most basic substances in the universe.
The periodic table of elements contains only elements, not compounds of these elements. CH4 is a compound made up of the elements carbon (C) and hydrogen (H), and is commonly known as methane, a gas that can be produced synthetically in a number of ways, and is also produced naturally by the decomposition of organic matter, and by the digestive systems of ruminants. Cows, for instance, release methane gas through flatus (farts).
A few elements normally exist as molecules: hydrogen, nitrogen, oxygen, and the halogen gasses of group 7 on the periodic table. Two atoms of these gasses will combine to form a molecule (such as H2, O2, Cl2), but since they are the same type of atom, they are not compounds.
Father as in who created it? That would be Mendeleev, he even named the 101st element after himself. Improving: Mendeleev, was the father of the periodic table of elements, he discovered this method of organizinging the elements by playing a game of solitare with the chemical symbols.
The symbol of elements can be found on a periodic table.
Oxygen, hydrogen, nitrogen, chlorine, and fluorine all form diatomic molecules.
You find elements on the periodic table. Molecules are two or more of these together including diatomic elements such as I2.
The right side (non-metal side)
The elements that form diatomic molecules are hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, iodine, and astatine. The chemical formula for each diatomic molecule is H2, N2, O2, F2, Cl2, Br2, I2, and At2.
The diatomic molecules in the periodic table are also known as the Fab 7. They are in a row such that they create kind of an upside down L (excluding Hydrogen at the top left): Nitrogen, Oxygen, Fluorine, Chlorine, Bromine, Iodine, and lastly, Hydrogen.
The periodic list/table is a list of the elements and nothing more or less.
diatomic moleculeA molecule containing two atoms is a diatomic molecule. These types of molecules can also contain more than two atoms.
Hydrogen is the first element in the periodic table. It stays as diatomic molecules.
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.
Bromine is non metal which is liquid.It is halogen.It belongs to group-17.There are only two elements in the periodic table that are non metals. They are bromine and mercury. From those, bromine is the only non metal.There are only two liquid elements in the periodic table. The only non metal liquid is Bromine. Bromine stays as a diatomic molecules.
Group number 17 of the periodic table is a poor conductor because all are non-metals and diatomic molecules.
in the Periodic Table there are 7 diatomic elements..they are hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, iodine
