There are 6 hydrogen atoms, 3 phosphorus atoms, and 4 oxygen atoms in the formula H3PO4.
A molecular formula.
It tells what elements are present in a molecule and how many atoms of each element are present.
I think it's the substance. Had this as a science Question...
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.
The answer is four. The molecular formula of any element or compund gives you the number of atoms of each element in a molecule. For phosphorus the most common form is P4 . The molecules are tetrahedral with a P atom at each apex.
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.

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.
how many
You can determine the number of atoms of each element in a compound by using the chemical formula of the compound. The subscripts in the formula indicate the number of atoms of each element. For example, in H2O (water), there are 2 hydrogen atoms and 1 oxygen atom.
A molecular 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.
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.
the formula tells youwhich elements make up a compound as well as how many atoms of each element are present.
the formula tells youwhich elements make up a compound as well as how many atoms of each element are present.
Technically no, molecular formula tells you how many atoms of each element compose a molecule. For example O: oxygen C: Carbon H: hydrogen Carbon dioxides molecular formula is CO2 Atmospheric oxygen is O2 Glucose's molecular formula is C6H12O6
It tells what elements are present in a molecule and how many atoms of each element are present.
