Ions and Ionic Bonding

Why do ionic bonds form?

• so the number of protons equals the number of electrons
• to fill the outermost energy level
• so an atom can become unstable

An electron has what kind of charge?

• no charge
• positive 
• negative
• it depends

An atom that has gained or lost electrons is called ...

• a winner
• an isotope
• an ion

• remain neutrally charged
• 21

If an aluminum atom has 13 protons (+) and 10 electrons (-), what is it's charge?

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

What type of elements will form an ionic bond?

• Metals + Metals
• Nonmetals + Nonmetals
• Metals + Nonmetals
• None of the above
