Detailed explanation-1: -As a member of the transition metals family of elements in the periodic table, tungsten has an electronegativity of 1.7 according to Pauling, whereas the atomic radius according to van der Waals is 0.137 nm. Tungsten is an exceptionally dense element, even denser than gold.

Detailed explanation-2: -Ionic bonds form between atoms with an electronegativity difference > 1.7.

Detailed explanation-3: -What is the Electronegativity of Tungsten? Tungsten’s Electronegativty is 2.36. Electronegativity is a measure of how strongly atoms attract bonding electrons to themselves.

Detailed explanation-4: -The degree to which an atom attracts electrons in a chemical bond is described by electronegativity. If the difference in electronegativity is greater than 1.7, the character of the bond will be ionic. If the difference in electronegativity is between 0.4 and 1.7, the character of the bond is polar covalent.

Detailed explanation-5: -One way of estimating the ionic character of a bond-that is, the magnitude of the charge separation in a polar covalent bond-is to calculate the difference in electronegativity between the two atoms: = B − A.
