The electronegativity is 2.1 for H and 1.9 for Sb. Based on these electronegativities, What would be expected for SbH3?
1) have nonpolar bonds
2) be ionic and contain H- ions
3) have polar covalent bonds with a partial negative charges on the H atoms
4) be ionic and contain H⁺ ions
5) 5. have polar covalent bonds with a partial positive charges on the H atoms
