if two atoms that differ in electro negativity combine by chemical reaction and share electrons,the bond that joins them will be__________?
A) Metallic B) ionic C) a hydrogen bond D) non polar covalent E) polar covalent
E) polar covalent
If the electronegativity of the atoms is less than 1.7, the pair of electrons is shared, but it is more shifted to the more electronegative atom. In the case of ionic bonding electron pair is fully transferred
