) by a mathematical relation, which was later modified by Rydberg. where 'R H ' is the Rydberg's constant and 'n 1 ', 'n 2 ' are integers with values equal to or greater than 3 and ' l ' is the wavelengt..

Hydrogen atom (Z=1) has no neutrons. Number of protons = 1 Number of electrons = 1 Number of neutrons = 0 It has been reported that the hydrogen element has atoms with mass number 2 and 3 also i.e., Atoms of elements..

> Noble gases, some metals, carbon, silicon etc. have only one atom in their molecules. These are called monatomic molecules. Some elements have two atoms in their molecules. These are called diatomic molecules e.g., hydrogen (H 2 ), oxyge..

. Metalloids are the elements, which have properties that lie between those of metals and non-metals, e.g., arsenic, antimony, etc. Molecules of elements may consist of single atom, two atoms, or even more. All the hundreds of thousands of compounds existing,..

Experimentally it is determined that the mass of an atom is very small ranging from 1.7 x 10 - 2 4 g to about 4.0 x 10 - 2 2 g. These small masses are terribly impractical to work with. Thus, it became necessary to reduce the atomic masses into simp..

Atomicity of a Molecule of an Element - The number of atoms, which constitute one molecule of an element, is called its atomicity. Phosphorus: P 4 - 4 atomicity Sulphur: S 8 - 8 atomicity Oxygen: O 2 - 2 ..

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 su..

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 ..
