(i) By thermal dissociation
When molecular hydrogen is heated at 5000C,it dissociates into atomic hydrogen.
(ii) By electric discharge
At o.1 mm Hg to 1.00 mm Hg pressure
Hydrogen can exist as both atomic and molecular forms. In its atomic form, hydrogen exists as individual atoms (H). In its molecular form, hydrogen exists as diatomic molecules (H2), where two hydrogen atoms are bonded together.
There are three forms of Hydrogen (these are known as isotopes). These are normal hydrogen, deuterium and tritium.
To make molecular hydrogen water at home, you can use a water ionizer or a hydrogen water generator. These devices use electrolysis to infuse water with molecular hydrogen gas, creating hydrogen-rich water. Simply follow the instructions provided with the device to produce your own hydrogen water at home.
molecular mass
Atomic weights refer to ATOMS. Water is a MOLECULE made up of 3 atoms, it therefore does not have an atomic weight, it has a MOLECULAR weight.You calculate the molecular weight by adding up the atomic weight of all the atoms in the molecule.Waster is made up from 1 atom of Oxygen (atomic weight 16) and 2 atoms of Hydrogen (atomic weight 1)16+1+1 = 18The molecular weight of water is therefore 18.-------------------------------------------------------------------------------------The atomic mass of H is 1.008, and the atomic mass of O is 16.So 1.008*2+16=18.016
Hydrogen can exist as both atomic and molecular forms. In its atomic form, hydrogen exists as individual atoms (H). In its molecular form, hydrogen exists as diatomic molecules (H2), where two hydrogen atoms are bonded together.
When hydrogen is liberated from a compound in a chemical reaction it invariably forms molecular hydrogen, H2, rather than atomic hydrogen.
The molecular mass of hydrogen gas is 2. A molecule of hydrogen gas contains two hydrogen atoms covalently bonded. Since each hydrogen atom has an atomic mass of 1 (as we can derive from the Periodic Table of Elements), the molecular mass of hydrogen gas as a molecule is 1 + 1 = 2.
The atomic mass of hydrogen is 1u. Atomic mass of bromine is 80u. Therefore, the molar mass of hydrogen bromide is 1+80=81u.
Hydrogen has by far the smaller molecular mass (and atomic number) making it the smallest element
The molecular mass of water (H2O) is 18, which means the total mass of one oxygen atom and two hydrogen atoms is 18. Since the atomic mass number of hydrogen is 1, the atomic mass of oxygen can be calculated as 16 (18 - 2).
There are three forms of Hydrogen (these are known as isotopes). These are normal hydrogen, deuterium and tritium.
gram molecular weight of C6H8O7=(atomic weigth of carbon X 6)+(atomic weigth of hydrogen X 8+(atomic weigth of oxygen X 7) grams
For H2 (natural occurring element Hydrogen) it is 2*1.00794 a.m.u = 2.01588 a.m.eThis means that 1.00000 mole H2 has a mass of 2.01588 grams

molecular mass
Well first of all a molecule doesn't have an atomic mass it has a molecular mass. It's molecular mass is found by adding up the atomic masses of all the elements that make up the molecule. These atomic masses are found on a periodic table. For example water has a formula of H20. This means it is made of 2 hydrogen atoms and 1 oxygen atom. Hydrogen has an atomic mass of 1 g/mol while oxygen has an atomic mass of 16 g/mol. So the molecular mass of water is 2 x 1g/mol + 1 x 16 g/mol = 18 g/mol
