Ionic and metallic bonds are universally weaker than covalent bonds
the verdict
REFUTED
the evidence says no
confidence 3/100
The claim that ionic and metallic bonds are universally weaker than covalent bonds is refuted, as bond strengths vary widely by specific system and many ionic and metallic interactions match or exceed the strength of typical covalent bonds.
