Question

In chemical formulas, there are often subscript numbers (such as the 2 in H2O, or the 6, 12, and 6 in C6H12O6).

What do these subscript numbers mean? What information do the tell us?

Subscript numbers tell us how many of the element to their upper-left there are in the molecule.

Subscript numbers tell us the electrical charge of the element to their upper-left

Subscript numbers tell us how many of the element to their upper-left there are.

Subscript numbers tell us how many of the element to their upper-right there are in the molecule.

Subscript numbers tell us how many of the element to their upper-right there are.

Answer 1

Answer: Subscript numbers tell us how many of the element to their upper-left there are in the molecule.

Step-by-step explanation:

In chemical formulas ,the subscript numbers tells us about the total number of atoms of an element present in a molecule. Number subscript is always written after the symbol of an element in the bottom of the symbol.

For example:
`H_2O` , is a chemical formula of a water molecule which is made up two hydrogen atoms and one oxygen atom. '2' is written after and in bottom of the hydrogen element's symbol 'H'. Hence Subscript numbers tell us how many of the element to their upper-left there are in the molecule.
