the purpose of a subscript is to tell how many atoms of that chemical is used in the formula
The number of atoms of the same element in the molecule ~APEX
A subscript indicates the number of atoms or ions of an element in a chemical formula.
The subscript denotes how much of that atom is in the molecule.
How does a subscript affect the element just before it?
1. You cannot change the subscript just to help you balance the equation. You can only balance an equation by using whole-number coefficients written at the beginning of a substance. 2. If no subscript is present, you can't just add one to help you balance the equation for same reason listed above.
It is called a subscript. For example: In the formula for water (H2O), 2 is the subscript indicating that there are 2 hydrogen atoms in the compound .
Not every chemical formula requires subscript. For example table salt is NaCl, sodium chloride. No subscript. But most chemical formulae do require subscript, such as water, H2O.
It is important never to change a subscript {note correct spelling} in a chemical formula when balancing a chemical equation, because changing a subscript produces a formula that specifies a chemical substance different from the one in the original equation.
The subscript denotes how much of that atom is in the molecule.
How does a subscript affect the element just before it?
Technetium-99 has not a chemical equation but an isotopic symbol. This is Tc with:- to the left, as a superscript, 99- to the left as a subscript, 43
A coefficient is the number that goes before an element when your balancing the equation. And a subscript is the number after the element. Subscripts are not changed when you balance the equation.
False. Subscript cannot be change to balance chemical equations. Only coefficients can be added to balance chemical equation.

By having the same numbers of atoms of each kind of element present in the equation in the written numbers (coefficient multiplied by subscript) of each kind of element on both sides of the equation.
The coefficient is a count of the number of molecules of each substance in a chemical process. The subscript is the number of atoms of an element in each molecule.

The subscript in a chemical formula refers to the _____.
