The organized way of elements of an atom is called the atomic structure of an element. An atom consists of a nucleus and a series of orbitals. The nucleus is situated in the centre of the atom and orbitals are surrounding them. Further, the atom of an element is made up of three ...
Each chemical element has a unique number of protons in its nucleus, its 'atomic number'. For instance, the element carbon with six protons has the atomic number six. However, single elements can have different numbers of neutrons in the nucleus. For example, carbon has three naturally occurri...

One of these decompositions is invariant with respect to the symmetry elements of the overall boundary structure, while the other is not. The continuity of boundary structure and grain boundary dislocation Burgers vectors, in particular misorientation ranges, is recognized by selecting the same set of...

An atom is the smallest particle of an element that retains its identity in a chemical reaction. 1. All elements are composed of tiny particles called atoms. 2. Atoms of the same element are identical. 3. Atoms of different elements can physically mix in simple whole number ratios to ...
Atoms of an element are all the same in terms of shape and size and atoms of different elements differ in size and shape. Elements are characterised by mass of their atoms so all the atoms of an element have identical weight. Different elements have atoms of different atomic weight. Atoms ...
