Ionic Bonds

What are ionic bonds?

• valence electrons transferred between atoms

• Inner most electrons transferred between atoms

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

When the number of electrons equals the number of protons the atom has what charge?

• sponge bob

• positive charge

• negative charge

• neutral charge

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

• a winner

• an isotope

• an ion

• a loser

For an atom to LOSE and electron what has to be broken?

• The attraction between the electrons and protons

• the attraction between the electrons and neutrons

• The attraction between the protons

• The attraction between the electrons

How do positive ions form?

• by gaining electrons

• getting compliments

• by losing electrons

• gaining more protons

How do negative ions form?

• by losing electrons

• by gaining electrons

• by gaining protons

• by being a bully
