ratio of hydrogen atoms to oxygen atoms

Like halogens, hydrogen is diatomic (H 2 ) whereas metals are monoatomi..

Atomicity is the number of atoms of an element present in one molecule of that element. They can be monoatomic (He), diatomic (H 2 ), triatomic (O 3 ) and polyatomic (S 8 ..

Langmuir ,in 1915, obtained atomic hydrogen by dissociating on a hot filament of tungsten or platinum. The dissociation of molecular hydrogen is an endothermic process. The atomic hydrogen is stable only for a fraction of a second and immediately..

. Examples: CO 2 , H 2 O, SO 3 , HCl Depending upon the number of atoms in one molecule of the element it can be classified a..

Atom is the smallest particle of an element, which may or may not have independent existence. It is made up of subatomic particles like electrons, protons and neutrons. Atoms of one type of element differ from those of the other due to different number of subatomic particles. ..

On reaction with the other substances, sulphurous acid takes away an atom of oxygen from them, thereby reducing these substances...

The distance from the centre of the nucleus to the outermost shell of an atom is called the atomic radius of that atom (Fig. 2.1..

Atomic Mass - It is known that the atomic mass of an element/compound is not the mass of one atom or molecule of the said element/compound because they occur as a mixture of isotopes. As the atomic and molecular masses are expressed on a relative scale bas..

In view of new discoveries about atoms, Dalton's atomic theory was modified as given below: Atom is no longer indivisible as it has a complex structure of sub atomic particles (electrons, protons and neutrons). Atoms of the same element may posses d..
