Ionic Bonding

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

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
