Atomic Mass of an Element or Relative Atomic Mass
The atomic mass of an element is a relative quantity and is the mass of one atom of the element relative to the mass of one carbon-12 atom. Thus,Relative atomic mass (RAM) of an element is the number of times one atom of an ..

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 simple figures. Hydrogen..

Elements
"An element is a pure substance which is made up of only one kind of atoms having the same atomic number." "The smallest particle of an element is the atom which, has all the properties of that element." "An element cannot be broke..
Mass number
The sum of the number of protons and neutrons in the nucleus of an atom is called the mass number. It is represented by the letter A. Mass number (A)= Number of protons (p) + number of neutrons (n) From the knowledge of atomic number and mass number the number of elec..
Grouping of Some Elements
In some cases Mendeleev placed elements according to their similarities in properties and not in increasing order of their atomic masses, while some dissimilar elements were grouped together. Thus, the position of these elements was not justified. For exampl..
Atomic mass, mass number or nucleon number
The total number of protons and neutrons present in one atom of an element is known as its mass number. Mass number = number of protons + number of neutrons It can also be said that: Mass number = Atomic number + number of neutrons Atomic number and mas..
