Ionic Compounds What are
Chemical Bonds
Force that holds 2 atoms together
Attraction between + nucleus and – electron
Attraction between + ion and – ion
Valence electrons make bonds

Ionic compounds What
are chemical bonds? (cont)
Elements react to form a stable octet (noble gas configuration). The + and – charges act like opposite
poles of a magnet. Opposites attract strongly Likes repel strongly Strength diminishes with distance

Ionic Compounds
How are positive ions formed?
Atom loses one or more VALENCE electrons
Called a CATION Ion becomes more stable by losing
electrons (octet rule) Not a change in atom, Just an ion Loses all electrons in outer shell
Reactivity depends on ease of losing electrons
Transition metals usually form 2+ or 3+ ions shown with a (II) or (III)

Ionic Compounds How are
positive ions formed?
Group 1A loses 1 valence electron Group 2A loses 2 valence electrons Group 3A (13) loses 3 valence
electrons Group 4A (14) does not generally
make ionic compounds

Ionic Bonds How are
positive ions formed ? (Cont)
Transition metals give up the 4s electrons to make pseudo-noble gasses

Ionic Bonds How do
negative ions form?
Atoms gain negative electrons Nonmetals have a great attraction for
electrons Adding electron fills up the shell = stable
Called an ANION Naming: change name to end in –ide Gaining enough electrons to fill outer
shell (octet rule) 7A gains 1 6A gains 2 5A gains 3

Ionic Compounds Ionic compounds are Metal+ and Nonmetal- Metals make Cations
Groups 1A (1) – 3A (13) and all Group D elements Form + ions
Nonmetals make Anions Group 5A (15) - 7A (17)
Nobel Gasses (Group 8A/18) do not form compounds. Why?
