You count the little number next to the element and you count how many there are add them together and there you have it. But if you are balancing an equation than you must use those numbers but do not add them together

∙ 13y agoThere are far too many to count. So instead you use the weight of an individual molecule or atom(whatever the item is made of). You then weigh the item or sample and you then know approximately how many atoms/molecules are in the sample.
if given a formula like
FeSO4 you count three elements- Fe, S and O which means that you have a polyatomic
ion and in this case it's called sulfate. The number of atoms of each element are Fe = 1,
S = 1 and O = 4

How many atoms of each element are shown in the formula for calcium carbonate?
There are five atoms
How many atoms each element are in the formula 2na2so4?
2
What is a molecular formula?
The molecular formula specifies the actual number of atoms of each element in a molecule.
The number of atoms of each element present in the molecule is indicated by what?
A subscript number after each atomic symbol in a formula for the compound.
What three things does a chemical formula tell you?
The type and the number of atoms of each element present.
How do you find how many atoms of an element are in a compound if you are only given the name and not the formula?
Draw the structure based on the name. Then count the number of times each atom appears in the structure. Alternately, you can determine the formula from the structure - and then count all atoms of each type.
What do you count to decide whether or not an equation is balanced?
If you count all of the atoms of each element on the left and all the atoms of each element on the right and the numbers on the left and right are equal for EVERY element, then the equation is balanced.
How many atoms of each element are shown in the formula for calcium carbonate?
There are five atoms
A cubic unit cell contains atoms of element A at each corner and atoms of element Z on each face What is the empirical formula of the compound?

How many number of atoms of each element in a chemical formula?
1
How many atoms each element are in the formula 2na2so4?
2
What does the subscript indicate in the chemical formula?
The number of atoms of that element in the molecule
What is an atom inventory?
Is a count of the numbers of atoms of each element in a compound or in a chemical reaction.
A chemical formula tells what make up a and the exact of atoms of each element in a unit of compound?
A chemical formula tells what elements make up a compound and the exact number of atoms of each element in a unit of compound. :)
What is the formula of imperical?
The simplest ratio of atoms of each element within a compound
What shows how many atoms of each element are in a unit of a 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.
