What shows how many atoms of each element are in a unit of substance?
The chemical formula shows you this. The subscripted number next to each element shows how many atoms are present in a molecule or formula unit. If no number is shown, then only one atom of that element is present.

What indicates all the elements in the compound as well as how many atoms of each element are present?
A molecular formula.
How do you determin how many atoms in each element?
To determine how many atoms are in each element of a compound, you can analyze its chemical formula. The formula indicates the number of atoms of each element present; for example, in water (H₂O), there are two hydrogen (H) atoms and one oxygen (O) atom. If the formula includes subscripts, they represent the number of atoms for the corresponding element, while parentheses may indicate groups of atoms that are counted together. For elements in their pure form, like O₂, the subscript directly tells you the number of atoms, in this case, two oxygen atoms.
What does a chemical compound formula tell you?
It tells what elements are present in a molecule and how many atoms of each element are present.
How is a formula of a compound written?
The formula of a compound is written using the symbols of the elements present in the compound and subscript numbers to represent the ratio of each element in the compound. The subscript numbers indicate how many atoms of each element are present in a molecule of the compound.
What does the subscript 2 indicate int he compuonds mgcl2?
In chemical compounds, subscripts indicate how many of that element are present in the compound, compared to the rest of the compound.In MgCl2, the subscript indicates that there are two chlorine atoms for every atom of magnesium.
How can the number of atoms of an individual element be determined by using a chemical formula?
The subscript number after the element symbol, such as the 2 in H2O, tells how many atoms in each molecule. In the example, the 2 refers to H (hydrogen). If there is no number present, then 1 is implied. So H2O has 2 hydrogen and 1 oxygen.
What do the prefixes in a covalent compound name tell when writing the chemical formula?
The prefixes in a covalent compound name indicate the number of each element present in the compound. The prefixes are used to determine the subscripts in the chemical formula, specifying how many atoms of each element are bonded together.
How many atoms are there of each element of iron?

How many atoMs are represented in Na2S2O3.5H2O?
There are a total of 25 atoms in Na2S2O3.5H2O. This can be calculated by adding the number of atoms present in each element: 2 sodium atoms, 2 sulfur atoms, 3 oxygen atoms, and 18 hydrogen atoms (5 water molecules with 2 hydrogen atoms each).
How many atoms are there in a mixture of two elements?
The number of atoms in a mixture of two elements depends on the amount of each element present. You can calculate the number of atoms by using Avogadro's number (6.022 x 10^23 atoms/mole) and the chemical formula and quantities of each element in the mixture.
