Interpretation:
The name of the ionic compound formed from the ions
Concept Introduction:
Chemical formulas and names for ionic compounds containing polyatomic ions:
Ionic compounds containing positive and negative charges present must add to zero.
If more than one polyatomic ion is present in a compound, the chemical formula can be written as a polyatomic ion is enclose in parentheses and a subscript, placed outside of the parentheses. Example-
Sometimes same element is present in two different locations. For example,

Whenever chemists observed atoms reacting with each other, they noticed that the sum of their group numbers usually equaled eight, or multiples of 8 (16, 24, 32, 40, etc.). This is called The Rule of Eight. How does this Rule of Eight work in understanding chemical formulas?2. Chemical formulas are written to show how many atoms of each element are bonded together to make a molecule of a substance. For example, C6H12O6 is the chemical formula for one molecule of sugar.3. Look at water: H20. By looking at this formula, you know that it takes _____ hydrogen atom(s) to bond with _______ oxygen atom(s).4. Now, add the group numbers. Hydrogen has a group # of 1A. Oxygen has a group number of 6A. Two hydrogens (1 + 1) and one oxygen (6) equals a total of 8. The Rule of Eight!5. Try another simple one, table salt (sodium chloride, NaCl). The formula tells you that it takes ______ sodium atom(s) to bond to ______ chlorine atom(s). Add the group numbers: The group # for…arrow_forward
