A molecular formula shows this information. In sulfuric acid, for example, the formula is H2SO4 as you'll learn to write it. There is hydrogen (H), sulfur (S) and oxygen (O) in it, and there are specifically 2 atoms of hydrogen, one atom of sulfur, and 4 atoms of oxygen. You already guessed (and correctly!) that those numbers, the numerical subscripts, tell an investigator how many of those particular atoms are in the molecule of sulfuric acid.

∙ 6y agoThe elements that make up a compound and the exact number of atoms of each element in a unit of the compound are shown in the compound's formula unit for an ionic compound) or molecular formula (for a covalently bonded compound). These characteristics of the compound are show by:
use in the formula of at least one* instance of the atomic symbol for each element in the compound; and,
for each element with more than one atom present in a unit of the compound, also more than one instance of the symbol in the formula and/or a subscript number after the atomic symbol.
The subscript numbers are chosen so that the sum of:
(a) all the explicit subscripts for each element symbol for the same element; plus
(b) the number 1 for each appearance in the formula of the same atomic symbol without any explicit subscript,
shows the exact number of atoms of that element in a unit of the compound.
________________
In order to show differences in chemical bonding, a symbol for the same element is conventionally written more than once in the formulas for some compounds, such as ammonium nitrate, with formula NH4NO3, and acetic acid, with formula CH3COOH.

∙ 9y agoThe exact number of atoms of each element in a unit of the compound can be shown in a chemical formula. Through the use of symbols, a chemical formula represents the proportions of atoms in a compound. For example, the chemical formula for water H2O indicates there are two hydrogen atoms and one oxygen atom.

What is the least number of atoms in a compound?
A compound must have at least two atoms of different elements.
Is copper oxide an element or a compound?
Copper is a chemical element. It can be a compound but copper is usually known as a chemical element.
Hydrogen compound or element?
Element It is in the periodic table of elements. It contains only hydrogen atoms. Compounds must contain two or more elements, so it isn't a compound.
How is a compound different from an element-?
A compound is different from an element in that a compound is made up of several elements. An element is a base atom only. Think of a compound as a living room set and an element as a couch only.
What are the elements of compounds?
The elements of a compound are the simplest components that it can be broken down into by chemical means. The atoms of an element have the same number of protons and electrons and have the same behaviors.
Elements a compound contains and the exact number of the atoms of each element in a unit of that compound is called what?
That is called a formula.
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. :)
The elements that make up a compound and the exact number of atoms of each element in a unit of the compound can be?
Subscript (:This is a subscript: (Na2) the "2" is the Subscript.
What is a method for representing a compound with atomic symbols and subscripts that shows the elements and the number of atoms of each element that combine to for a compound?
a chemical formula
Why Elements are aleways combined in a compound with another element why does this occur?
That's because of the way "compound" is defined. If atoms of an element combine with other atoms of the SAME element, then it's not called a "compound".
Does an element become a compound when the type of atoms is changed?
Yes, the element changes to compound when atoms of it changes because compound is made up of different types of element and the element is made up of different types of atoms when the atoms are changed the element also changes and different types of elements are made due to this the element is changed to a compound.
How does the chemical formula of a compound relate to the relative number of atoms in the compound?
Chemical formulas consist of chemical symbols and numbers. The symbols represent the elements in the compound. The numbers indicate the quantity of atoms of each element in the compound.
What distinguishes a compound from an element?
An element consists of only one type of atom e.g. gold contains only gold atoms. A compound is two or more elements chemically combined eg. Carbon Dioxide, CO2, which contains one Carbon atom and two Oxygen atoms.
What do linked atoms form in compounds?
Linked up atoms form matter called a compound
How are subscripts used in a compound?
They show the number of atoms that element has in that compound.
What is the least number of atoms in a compound?
A compound must have at least two atoms of different elements.
WHAT CHEMICAL shows the relative number of atoms of each element in a compound.?
It is important to know the relative number of atoms of each element in a compound for the chemical composition.
