An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the … See more Pauling electronegativity Pauling first proposed the concept of electronegativity in 1932 to explain why the covalent bond between two different atoms (A–B) is stronger than the average of the A–A and the … See more Periodic trends In general, electronegativity increases on passing from left to right along a period and decreases on descending a group. Hence, fluorine is the most electronegative of the elements (not counting noble gases), whereas See more 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 … See more • Jolly, William L. (1991). Modern Inorganic Chemistry (2nd ed.).
