Ionic Electron Transfer

Which of the following is NOT a step in forming an ionic bond?

• One atom shares its electrons with another one.
• Opposite charged ions form due to e- transfer
• One atom gives electrons to another one
• Opposite charged ions attract

Why do ionic bonds form?

• So the number of protons equals the number of electrons.
• To stabilize the atom with a full outer shell.
• So an atom can become unstable.
• So atoms will stick together to form molecules.

What is the charge on a noble gas & why?

• 0; they don't exchange electrons
• +1; they give away an electron
• -1; they gain an electron
• 1; they form only single bonds

An ionic bond is the attraction between:

• oppositely charged ions
• similarly charged ions
• neutral ions
• neutral atoms

Which of the following describes the strength of an ionic bond?

• Middle - Each atom shares an octet
• Middle - One atom gains an octet & the other loses.
• Weakest - it only forms because of another bond forming
• Strongest - each atom receives a "permanent" octet.
