Electronegativity is mainly used for two purposes; To predict if an atom will form an ionic or a covalent bond. The element which has the highest electronegativity value is Fluorine with 3.98 χ. Most of the time, the electronegativity values of elements are given in the periodic table. Electronegativity (Pauling Scale): 2.36 ... Tungsten carbide (WC or W 2 C) is extremely hard and is used to make drills. ‘Electronegativity is probably the most important chemical property of the elements,’ says Oganov. Electronegativity (Pauling scale) The tendency of an atom to attract electrons towards itself, expressed on a relative scale. Tungsten is a greyish-white lustrous metal, which is a solid at room temperature. Hope it helps! Just remember, the electronegativity of the elements increase as you go up and to the right of the periodic table. osti.gov journal article: relationship between surface potential and electronegativity for adsorption on tungsten single crystals. So consider the following scheme: Na,K
