The chemical symbol for Nickel is Ni. Atomic Mass of Nickel Atomic mass of Nickel is 58.6934 u. Atomic Radius Trend on the Periodic Table The size of neutral atoms is drawn from the atomic radius, which is half the distance between two atoms that are just touching each other. If you look at the table, you can see there is a clear trend in atomic radius. Atomic radius is one of the periodic properties of the elements. Sizes of atoms. resources.

For instance, the radii generally decrease rightward along each period (row) of the table, from the alkali metals to the noble gases; and increase down each group The atomic radius of the elements increases as we go from right to left across a period and as we go down the periods in a group. The increase in atomic size going down a column is also due to electron shielding, but the situation is more complex because the principal quantum number n is not constant.

As period number increases , number of shells increase , so atomic size increases . As we move from left to right in a period , number of electrons in shell increase , so effective nuclear charge ( force of attraction between nucleus of atom which has +ve charge and electrons which have -ve charge) increases so shells are closer to nucleus and atomic size is less .

As we saw in Chapter 2, the size of the orbitals increases as n increases, provided the nuclear charge remains the same. In group 1, for example, the size of the atoms The atomic size increases due to shielding effect and balances the decrease in size due to increase in nuclear charge to about 80%. Thus moving from left to right in a period, there is a very small decrease in size and it may be considered that size almost remains the same. This will decrease the radius of an atom.
