WebCompounds such as magnesium oxide ( M g O ), sodium chloride ( N a C l ), and calcium fluoride ( C a F 2 )are examples of this. Usually, if the difference in electronegativity exceeds 2.0, the bond is likely to be ionic. If the difference is less than 0.5 then the bond will be a non-polar covalent bond. WebSo, that is part of the issue. Unlike electronegativity, the electron affinity does not have a strong periodic value. The electron affinity measures the energy released when an electron is captured by the atom (or a molecule), forming an anion with a 1− charge. This is not necessarily directly related to the "willingness" for the element to ... dba – the barge association – dba barges.orgWebWhich statement correctly and completely identifies a trend?
