Introduction :
Nickel was accidentally discovered by Axel F Cronstendt when he was trying to isolate the element from its mineral ore kupfernickel in Sweden taking it to be copper. Nickel is mostly available in the pentlandite [(Ni, Fe)9S8] and garnierite ores found in countries like South Africa, Russia, Australia and Canada. It was discovered 250 years ago. It is the fifth most abundant element on earth.
As the atomic number of nickel is 28 it has 28 protons and 28 electrons. It has 31 neutrons in the atom's nucleus. The electrons assigned to different orbitals are 2, 8,16,2. The electron configuration of nickel can be written as 1s2 2s2p6 3s2p6d8 4s2 . The only Ferro-magnetic elements are nickel, iron & cobalt and among them nickel is supposed to be least magnetic.

Structure for Atomic structure of Nickel
Nickel
is a group 10 element and is one of the transition elements holding an
atomic number of 28. With an atomic number 28, nickel has 28 electrons
in various energy levels or these electrons are distributed in the
orbitals of the atom.

Atomic structure of Nickel – properties and uses
Properties:
Nickel
is corrosion resistant but it is soluble in acids. Alkalis do not
affect Nickel though. 58.6934is the atomic mass of nickel. 2732 degree
Celsius is its boiling point. 1453 degree Celsius is its melting point.
6.59 cm3/mole is its molar volume. Its density is 8.9g/cc.
Uses of Nickel:
Electroplating
and for formation of metal alloys nickel is used because of its
resistance to corrosion. It is also used as catalyst in nickel-cadmium
batteries. It is also the main constituent in coins. Because of
durability, strength and corrosion resistance nickel alloys are the most
sought after compared to other alloys. In animals, nickel along with
iron plays an important role of transporting oxygen in blood. It is part
of enzyme functioning in plants & animals. Whole grains such as
oats are excellent source of nickel. It is also part of genetic code DNA
& RNA. In many cordless appliances, nickel-cadmium batteries are
commonly used.
