The atomic structure of an element is all about the composition of its nucleus as well as the array of its electrons around the nucleus. This mainly constitutes of electron, proton, and neutron. It has been rightly said that the foundation of chemistry is an atom. Since all the living as...
This chapter discusses atomic structure and chemical bonding. The wave-mechanical treatment of the hydrogen atom leads to a definition of a series of electronic energy levels or orbitals that a single electron can occupy. The orbitals are grouped into shells and are designated by a principal ...
1.3Molecular structure Having sorted out ideas about elements and compounds in terms of atoms and molecules, attention shifted tosynthesis— the making of new compounds, and progress thereafter was rapid, especially in thechemistryof compounds containing the element carbon, what we call OrganicChemistry...

Chemical element - Geochemical Cycle, Atomic Structure, Reactivity: The preceding discussion has shown that at the time of formation of the Earth the chemical elements already had been considerably fractionated: the universe consists almost entirely of h
Boron is an element of chemistry that has atomic number 5. The chemical symbol of elemental boron is B. It is dark in colour, brittle, lustrous metalloid in its crystalline form on the other side; when it is amorphous boron, it is found in powder form coloured in brown. It is one of...
(chemistry) The individual structure which constitutes the basic unit of any chemical element. (mathematics) An element, A, of a measure algebra, other than the zero element, which has the property that any element which is equal to or less than A is either equal to A or equal to the...
