Question

Identifying lonic Compounds in Solution 1. Ions are chemical species that carry an electrical- . charge. Cations have a Anions have a Metals generally take on a 2. charge. 3. charge while nonmetals will take on a charge. 4. Ionic compounds are composed of a positive ion and a negative ion. When the ions combine to form a compound the charges must balance out. The charges on individual ions are shown below. For each compound, circle the correct formula (the formula in which the charges are balanced). Barium chloride barium ion (Ba2+) and chloride ion (CI) BaCI BaCI, Ba,c lithium ion (Li) and bromide ion (Br) Lithium bromide LiBr LiBr, Li,Br Aluminum bromide AlBr AlBr AlBr, A student is working with the ionic compound aluminum sulfide, which is made up of alumi- aluminum ion (Al3+) and bromide ion (Br) Al,Br, 5. num cations (Al+) and sulfide anions (S) To form aluminum sulfide the ions must combine as: AIS (AP ) ALS (A A ALS, (AP AP )
