What does a numerical subscript following an element symbol in a formula mean?

Answer 1

The subscript in a chemical formula represents the amount of that atom in that compound's formula.

Answer 2

It is similar to the subscript next to an element, it indicates how many of the group or polyatomic ion in parentheses are present in the formula.

As an example, calcium hydroxide is Ca(OH)2 The subscript indicates that this formula contains two hydroxide ions.

Answer 3

The numerical subscript following an element's symbol is either the number of atoms of that element in one molecule of a covalent substance, or it is the ratio of ions in an ionic compound (ionic compounds do not form molecules). For example, the formula for the covalent (molecular) compound glucose, C6H12O6, means there are 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms in one molecule of glucose. For an ionic compound, such as copper I oxide, Cu2O, the subscripts mean that the ratio of copper to oxygen ions is 2Cu:1O. A general rule of thumb in determining whether a substance is covalent (molecular)or ionic, is that covalent substances don't contain metals, and ionic compounds usually contain a metal and a nonmetal.

Answer 4

Subscript in a chemical formula shows the amount of atoms of that type in each molecule. (H2O means 2 Hydrogen atoms and a single Oxygen atom because of the "subscript" number 2)

Answer 5

it is how many of that element are in the formula(:

Answer 6

Usually, it describes the numbers of a particular elements that are required to make a substance. H2O states there are two hydrogen atoms and one oxygen atom to make up water.

Answer 7

Subscripts indicate the number of atoms or ions in a molecule or formula unit. They can also indicate the number of moles of atoms or ions in one mole of the compound.

Answer 9

The meaning is number of atoms.

Answer 10

The subscript numeric is to denote how many of the element before the subscript is in the compound. hope this helps
