What do subscripts represent in a ionic formula?
The numbers appearing as subscripts in the chemical formula indicate the number of atoms of the element immediately before the subscript. If no subscript appears, one atom of that element is present.
How can you tell the charge of an ion?
There is a quick way to work out what the charge on an ion should be: the number of charges on an ion formed by a metal is equal to the group number of the metal. the number of charges on an ion formed by a non-metal is equal to the group number minus eight.
What do the subscripts represent?
Subscripts are important numbers in formulas, especially when you’re trying to understand how many atoms of an element are present. A subscript is a number to the right and below the abbreviation of an element that indicates the number of elements that are present
Do subscripts represent ions?
How do subscripts represent the charge balance of ions? To balance the charges of ions the number of electrons lost is equal to the number of electrons gained. The number of ions needed to accomplish this is represented by the subscripts.
