There are two types of covalent bonds. What are the two types?

• Ionic

  Polar

• Polar

  Non Polar

• Non Polar

  Ionic

• Electronegative

  Ionic

For nonpolar covalent compounds, why are the electrons shared equally between the atoms in the compound?

• the elements have very different electronegativities so the shared electrons sit closer to the atom with the higher electronegativity.

• the elements have very different electronegativities so the shared electrons sit in the middle of the atoms.

• the elements have similar electronegativities so the shared electrons sit closer to the atom with the higher electronegativity.

• the elements have similar electronegativities so the shared electrons sit in the middle of the atoms.

• Polar

• Non Polar

In a polar covalent bond, describe the electrons.

• the elements have similar electronegativities so the shared electrons sit in the middle of the two atoms.

• the elements have similar electronegativities so the shared electrons sit closer to the atom with the higher electronegativity.

• the elements have very different electronegativities so the shared electrons sit in the middle of the two atoms.

• the elements have very different electronegativities so the shared electrons sit closer to the atom with the higher electronegativity.
