1) Metallic 2) Ionic 3) Covalent 4) Coordinate
5. The transfer of electrons from a metal to a nonmetal will result in the formation of
1) Hydrogen bond 3) Ionic bond
2) Covalent bond 4) Metallic bond
6. Two atoms with an eletronegativity difference of 0.4 form a bond that is
1) Ionic, because electrons are shared 3) Covalent, because electrons are shared
2) Ionic, because electrons are transferred 4) Covalent, because electrons are transferred
7. Two atoms share electrons equally, the bond formed is mostly
1) Polar and covalent 3) Metallic and covalent
2) Ionic and covalent 4) Nonpolar and covalent
8. Which type of bond exists in a molecule in which electrons are shared unequally between the two
atoms of the molecule?
1) A polar covalent bond with an electronegativity difference of zero
2) A polar covalent bond with an electronegativity difference greater than zero
3) A nonpolar covalent bond with an electronegativity difference of zero
4) A nonpolar covalent bond with an electronegativity difference greater than zero
9. When one atom loses one or more electrons to another, the bond formed between the two atoms is
best described as
1) Ionic with electronegativity difference of greater than 1.7
2) Ionic with electronegativity difference of less than 1.7
3) Covalent with electronegativity difference of greater than 1.7
4) Covalent with electronegativity difference of less than 1.7
10. Atom X bonds with another atom X to form X2 molecule. The bond in this molecule is
1) Polar because electrons are shared equally
2) Nonpolar because electrons are shared equally
3) Polar because electrons are shared unequally
4) Nonpolar because electrons are shared unequally
