Question

Write three differences between Ionic bonding and covalent bonding (electrical conductivity)

Answer 1

Ionic BondCovalent BondDefinitionA chemical bond between two dissimilar atoms in which atom gives up an electron to another.A covalent bond is a chemical bond that involves the sharing of electrons between two similar atoms.OccurrenceA metal and a non-metalTwo non-metalsPolarityHighLowShape of moleculeNo definite shape, lattice structuresDefinite shapeElectrical conductivityHighUsually noneThermal conductivityHighUsually lowMelting point of substanceVaries, but usually higher than covalent compoundsVaries, but usually lower than ionic compoundsBoiling point of substanceHighVaries, but usually lower than ionic compoundsSolubility in waterHighVaries, but usually lower than ionic compoundsState of substance at room temperatureUsually solidSolid, liquid, gas

Answer 2

Ionic bonds are formed by ions so they conduct electricity in their molten or aquestion solution state..

Covalent bonds are formed by molecules so they do not conduct electricity in their molten or aqueous solution state..
