The difference between a hydrogen atom and atomic hydrogen is that the "hydrogen atom" represents one atom of the chemical element hydrogen. Atomic hydrogen are isolated hydrogen atoms.

(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

the difference is that the substances is aparent only on the atomic or molecular level.

Hydrogen 1 is just a proton, it has an atomic mass of 1. Hydrogen 2 (deuterium) is a proton and a neutron, it has an atomic mass of 2.

In molecular orbitals electrons "move" across the whole molecule and in an atomic orbital they move around a single atom.

When hydrogen is liberated from a compound in a chemical reaction it invariably forms molecular hydrogen, H2, rather than atomic hydrogen.

Atomic mass is defined for atoms. Molecular mass is defined for molecules or compounds. Atoms bond with each other to form compounds.

The density of a gas is proportional to its molecular or atomic weight. Hydrogen has a molecular mass of about 2, while helium has an atomic mass of about 4. Therefore, helium is about twice as dense as hydrogen.

Since each water molecular contains two hydrogen atoms, the atomic mass of oxygen is 18 - 2 = 16.

Molecular mass of heavy hydrogen(deuterium) is 4 a.m.u. it's atomic mass = 2 a.m.u. Alternatively it can be stated that 1 mole of molecular hydrogen weighs 4 grams.

H is used to denote Hydrogen as in atomic form. However, naturally most light gases exist in a diatomic molecular form. Thus, H2 would denote the molecular form of Hydrogen.

no of neutrons in protium is 0 but not in deutirium and tritium.as the no of neutrons is difference between atomic mass and atomic number.

The difference between formula weight and molecular weight is in terms of type of compounds. Formula weight refers to the total of all atomic weights in the specific formula. Formula weight is used for ions rather than molecules. Molecular weight refers to the total of all atomic weights in the specific molecule.

Atomic mass is the mass of one atom of a particular element. For example, Oxygen has an atomic mass of 16u and Hydrogen has an atomic mass of 1u approximately (The actual value is 1.008 u). Molecular mass on the other hand is the sum of atomic masses of all the atoms present in a molecule. For example, H2O (Water) has a molecular mass of 18u approximately. It is obtained by multiplying the atomic mass of en element by the number of atoms present and then adding up the atomic mass of all the elements, i.e., (2x1) + (1x16) = 18u. We are multiplying 1 by 2 as there are 2 atoms of hydrogen in the molecule.

The atomic mass of hydrogen is 1u. Atomic mass of bromine is 80u. Therefore, the molar mass of hydrogen bromide is 1+80=81u.

Atomic oxygen is many oxygen atoms (O). Molecular oxygen is lots of oxygen molecules which are each made of two oxygen atoms bonded together (O2).

Atomic Hydrogen has one electron in its outermost orbit. Thus it can accept or donate one electron to reach the electronic configuration of the nearest inert gas. On the other hand, molecular hydrogen consists of two atoms of hydrogen linked together by a covalent bond. Thus, there is no extra electron for reactivity. For the above reason, atomic hydrogen can readily react with little amount of energy. Molecular hydrogen requires greater amount of energy so as to form atoms of hydrogen first which will react.

Hydrogen: atomic weight = 1,00794; 1 proton, 1 electron; atomic number 1 Oxygen: atomic weight =15,9994; 8 protons, neutrons and electrons; atomic number 8

18 moles of atomic hydrogen or 9 moles of molecular hydrogen is needed.

Helium is denser than hydrogen because as the molecular or atomic mass of a gas increases, density increases as well. Hydrogen has a molecular gas of about 2 g/mol while helium has an atomic mass of about 4 g/mol.

gram molecular weight of C6H8O7=(atomic weigth of carbon X 6)+(atomic weigth of hydrogen X 8+(atomic weigth of oxygen X 7) grams

Hydrogen has by far the smaller molecular mass (and atomic number) making it the smallest element

H2 does not have dipole moment so there is no allowed transition in infrared between vibrational levels.

The symbol for atomic hydrogen is H. But hydrogen as a gas molecule consists of two hydrogen atoms, so the formula for molecular hydrogen is H2.
