Under some definitions, the value of the radius may depend on the atom's state and context. [1] Atomic radii vary in a predictable and explicable manner across the periodic table. 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 number increases within the same period while moving from left to right, which in turn increases the effective nuclear charge. The increase in attractive forces reduces the atomic radius of elements. When we move down the group, the atomic radius increases due to the addition of a new shell. [5] [6] [7]
3.1 Atomic radius. 3.2 Ionisation energy. 3.3 Electron affinity. ... Metallic character increases going down a group and from right to left across a period.
For example, the atomic radius of the metal zirconium, Zr (a period-5 transition element), is 155 pm [11] (empirical value) and that of hafnium, Hf (the corresponding period-6 element), is 159 pm. [12] The ionic radius of Zr 4+ is 84 pm and that of Hf 4+ is 83 pm. [13] The radii are very similar even though the number of electrons increases ...

(Reuters) -Four men were convicted in Spain on Sunday in connection with the homophobic murder of a 24-year-old nursing assistant that sparked protests in cities across Spain and abroad.
A period 2 element is one of the chemical elements in the second row (or period) of the periodic table of the chemical elements.The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behavior of the elements as their atomic number increases; a new row is started when chemical behavior begins to repeat, creating columns of elements with similar properties.
