Numbers in a formula are used to denote when a molecule contains more than one atom of an element; the numbers are written below the element's symbol. For example, CO2is the formula forcarbon dioxide. It tells you that each molecule has one carbon atom and two oxygen atoms. Some formula...
A chemical symbol is used to represent an element. For combinations of elements, we use chemical formulas. Covalent and ionic compounds are expressed by using chemical symbols and subscripts.Answer and Explanation: We have a polyatomic ionic compound as we have a metal (calcium) and a polyatomic...

The symbol for the cation is written first. Ions combined: Mg2+, Br-, Br- Chemical formula: MgBr2 Note that the 2 in Br2 is written as a subscript. The charges of the ions are not included in the formula. This is usually the case when writing formulas for binary ionic compounds. ...
This is known as a word equation. By writing the symbols and formulae of the various substances in place of their names, we can convert this word equation into a chemical equation. Now, we know that the symbol of zinc is \(\text {Zn}\) ...
