Electropositivity is a measure of an element's ability to donate electrons, and therefore form positive ions; thus, it is antipode to electronegativity. Mainly, this is an attribute of metals , meaning that, in general, the greater the metallic character of an element the greater the electropositivity.

[10] [11] [12] As one moves from left-to-right across a period in the modern periodic table, the ionization energy increases as the nuclear charge increases and the atomic size decreases. The decrease in the atomic size results in a more potent force of attraction between the electrons and the nucleus. However, suppose one moves down in a group.
At zinc ([Ar] 3d 10 4s 2), the 3d orbitals are completely filled with a total of ten electrons. [ 39 ] [ 58 ] Next come the 4p orbitals, completing the row, which are filled progressively by gallium ([Ar] 3d 10 4s 2 4p 1 ) through krypton ([Ar] 3d 10 4s 2 4p 6 ), in a manner analogous to the previous p-block elements.
Elastic properties describe the reversible deformation (elastic response) of a material to an applied stress.They are a subset of the material properties that provide a quantitative description of the characteristics of a material, like its strength.

This is a list of chemical elements and their atomic properties, ordered by atomic number (Z).. Since valence electrons are not clearly defined for the d-block and f-block elements, there not being a clear point at which further ionisation becomes unprofitable, a purely formal definition as number of electrons in the outermost shell has been used.
