In the modern periodic table, the elements are listed in order of increasing atomic number. The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present). The number of protons determines how many electrons surround the nucleus, and it is the arrangement of these electrons that determines most of the chemical behavior of an element.
Atomic number = Number of protons. For example, in a sodium atom, there are 11 electrons and 11 protons. Thus the atomic number of Na atom = number of electrons = number of protons = 11. Atomic Number Orbital Energy Levels. The most common way of showing the arrangement of electrons in an atom is to draw diagrams like those shown in the diagram. Atomic Number of Nickel Nickel is a chemical element with atomic number 28 which means there are 28 protons and 28 electrons in the atomic structure. The chemical symbol for Nickel is Ni. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons.
In a periodic table arranged in order of increasing atomic number, elements having similar chemical properties naturally line up in the same column (group). For instance, all of the elements in Group 1A are relatively soft metals, react violently with water, and form 1+ charges; all of the elements in Group 8A are unreactive, monatomic gases at room temperature, etc. In other words, there is a periodic repetition of the properties of the chemical elements with increasing mass.
In the original periodic table published by Dimitri Mendeleev in 1869, the elements were arranged according to increasing atomic mass— at that time, the nucleus had not yet been discovered, and there was no understanding at all of the interior structure of the atom, so atomic mass was the only guide to use. Once the structure of the nucleus was understood, it became clear that it was the atomic number that governed the properties of the elements.
Atomic Number of Nickel is 28.
Chemical symbol for Nickel is Ni. Number of protons in Nickel is 28. Atomic weight of Nickel is 58.6934 u or g/mol. Melting point of Nickel is 1453 °C and its the boiling point is 2732 °C.

About Nickel
Nickel is a light grey color metal, which is quite strong and very resistive to corrosion. The name of the element is believed to take roots from the German expression meaning Devil’s copper. Despite the fact that nickel can be found in cells of all living organisms, this element is very carcinogenic even in small doses. It is impossible to find pure nickel on our planet, only in minerals, as well as on meteorites coming to our planet (one of them has landed in Canada and now provides about 15 per cent of the world’s nickel supply). Nickel used to be a key element for producing coins, and it is also used to produce batteries. Due its high resistance to corrosion, nickel is used to cover various metallic parts in order to prevent their corrosion. Numerous alloys of nickel have wide industrial uses.
