Ni Atomic Number

We remember from our school chemistry course that every element has its own specific atomic number. It is the same as the number of protons that the atom of each element has, so sometimes atomic number is called proton number. It is always the whole number and it ranges from 1 to 118, according to the number of the element in the Periodic Table. This number can be really important and something essential to know, in relation to a certain chemical element which is the issue of our interest at the moment.

The atomic number of nickel (Ni) is 28. The atomic weight of Ni is 58.70 grams per mole. See the Web Links and the Related Questions to the left of this answer for a Periodic Table and more. Explanation: Nickel is in the 4th energy level, d block, 7th column, this means that the electron configuration will end 3d8 with the d orbital being one level lower than the energy level it is on. N i = 1s22s22p63s23p64s23d8 N i = Ar4s23d8.

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. Atomic Mass of Nickel Atomic mass of Nickel is 58.6934 u. Ni-61 can be used for the production of the PET radioisotope Cu-61. Ni-62 is used for the production of the radioisotope Ni-63 which can be used as an XRF source, as an electron capture source in gas chromatographs and as a power source in microelectromechanical systems. Ni-58 can be used for the production of the radioisotope Co-58. The number of electrons in each of nickel's shells is 2, 8, 16, 2 and its electron configuration is Ar3d 8 4s 2. The nickel atom has a radius of 149.pm and its Van der Waals radius is 163.pm. In its elemental form, CAS 7440-02-0, nickel has a lustrous metallic silver appearance.

Why is this so? Why is the atomic number so important? First of all, it is the number that makes elements different from one another as it shows the number of protons in their nuclei. Also, knowing the atomic number of an element can give us an idea about the position of the element in the Periodic Table. Atomic number of an element never changes: for example, the atomic number of oxygen is always 8, and the atomic number of Chlorine is always 18. The atomic number is marked with the symbol Z, taken from a German word zahl (or atomzahl, which is 'atomic number' in German).
