Electronegativity is not a uniquely defined property and may depend on the definition. The suggested values are all taken from WebElements as a consistent set. Many of the highly radioactive elements have values that must be predictions or extrapolations, but are unfortunately not marked as such.
Electronegativity, symbolized as χ, is the tendency for an atom of a given chemical element to attract shared electrons (or electron density) when forming a chemical bond. [1] An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. The higher the ...
→ Atomic radius decreases → Ionization energy increases → Electronegativity increases ... Cl 3.16 Ar 4: K 0.82 Ca 1.00 Sc 1.36 Ti 1.54 V 1.63 Cr 1.66 Mn 1.55 Fe ...
Cl 2 O 3 is also produced when photolysing the solid at −78 °C: it is a dark brown solid that explodes below 0 °C. The ClO radical leads to the depletion of atmospheric ozone and is thus environmentally important as follows: [57] Cl• + O 3 ClO• + O 2 ClO• + O• Cl• + O 2. Chlorine perchlorate (ClOClO 3) is a pale yellow liquid that ...
Electronegativity: Pauling scale: 3.44 : Ionization energies: 1st: 1313.9 kJ/mol ; ... Oxygen is a chemical element with the symbol O and atomic number 8.
Chlorine (symbol Cl) is the second-lightest halogen. The element forms diatomic molecules under standard conditions , called dichlorine. It has the highest electron affinity and the one of highest electronegativity of all the elements; thus chlorine is a strong oxidizing agent .

It has a high ionisation energy (1251.2 kJ/mol), high electron affinity (349 kJ/mol; higher than fluorine), and high electronegativity (3.16). Chlorine is a strong oxidising agent (Cl 2 + 2e → 2HCl = 1.36 V at pH 0). Metal chlorides are largely ionic in nature. The common oxide of chlorine (Cl 2 O 7) is strongly acidic. Liquid bromine
