Structure of an atom

Three basic components: protons, neutrons and electrons make an Atom. The protons and neutrons are located in the nucleus or center of the atom while the electrons revolve around the nucleus in the orbits. The atom of each particular element will have a specific number of protons in its nucleus and an equal number of electrons in orbit if the atom is neutral (no charge). The exact approach in which the electrons are set around the nucleus is particularly significant in shaping the electrical characteristics of the element. Generally, each electron has its own orbits, but certain orbits are grouped together to form a shell.

Structure of an atom

For all of the elements that are known to survive, there can only be a utmost of seven shells. The shell closest to the nucleus can only hold 2 electrons while the second shell can hold a ceiling of 8 electrons. The third shell cannot embrace more than 18 electrons and the fourth can embrace no more than 32 and so on. The farthest shell of a particular atom is called the valence shell and the electrons in that orbit within this shell are referred to as valence electrons.

Structure of an atom

Take into account that the hydrogen atom has only one shell, while the carbon atom has two and the copper atom has four. Some of the shells include less than the utmost number of electrons allowed.

In any particular atom, the outer shell can never embrace more than 8 electrons. When accurately 8 electrons are present in the outer shell the atom is measured to be completely stable and it will neither give up nor accept electrons easily. Elements whose outermost shell has 8 atoms, are Neon and Argon. These elements are divided as inert gases and they resist any sort of electrical or chemical movement.

When an atom has 5 or additional electrons in its outer shell, it tries to pack its shell so it can arrive at a steady condition. Elements of this type make superior insulators because the individual atoms try to obtain electrons instead of giving them up. Therefore, the free progress of electrons from one atom to the next is repressed.

When an atom has fewer than 4 electrons in its outer shell it is inclined to give up these outer electrons effortlessly. Elements which have atoms of this type make good conductors because they enclose a large number of free moving electrons which can arbitrarily float from one atom to the next.
