Ions and Ionic Bonding

Ions and Ionic Bonding

Multiple Choice

An ionic bond is the attraction between:

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

Multiple Choice

An electron has what kind of charge?

• no charge
• positive 
• negative
• it depends

Multiple Choice

Atoms that gain electrons become...

• negatively charged
• positively charged
• remain neutrally charged
• 21

Multiple Choice

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

• a winner
• an isotope
• an ion
• a loser

Using the periodic table

You can predict the charge of an ion by using the group number the element belongs to.

For instance, all ions from elements in group 1 will have a +1 charge.

Group 0 already have a full shell so they do not form ions.

Common Groups and their Charges

• Group 1 will all lose 1 electron - +1 Ions

• Group 2 will all lose 2 electrons - +2 Ions

• Group 6 will all gain 2 electrons - -2 ions

• Group 7 will all gain 1 electron - -1 ions

Multiple Choice

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

Multiple Choice

What type of elements will form an ionic bond?

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

Multiple Choice

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

Multiple Choice

Beryllium, Be, will ____ valence electrons when forming an ionic bond.

• lose 4

• gain 4

• lose 2

• gain 2

Multiple Choice

If my charge becomes 2+ what does that say about me?

• I am stealing 2 electrons
• I am losing 2 electrons
• I am in period 2
• I have an atomic # of 2
