14. What type of bond is likely formed between 2 atoms with an electronegativity difference of 0.7? mostly covalent polar covalent nonpolar covalent ionic

When two atoms have an electronegativity difference of 0.7, the bond formed between them is typically classified as a polar covalent bond. Polar covalent bonds occur when the electronegativity difference between the two atoms is between approximately 0.5 and 1.7. This range indicates that the electrons are shared unequally between the atoms, resulting in a partial charge distribution. Therefore, the correct answer is:**polar covalent**
