Subscripts :)
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.
same number of each element
In this case, the equation is balanced.
each element has one atom of the element's name
It is important to know the relative number of atoms of each element in a compound for the chemical composition.
The type and the number of atoms of each element present.
In this case, the equation is balanced.
The number of protons in the nucleus of its atoms, which is its atomic number, defines each element. However, the nuclei of a given element may have varying numbers of neutrons.
The subscript in a formula typically indicates the number of atoms of an element present in a molecule. It is used to specify the ratio of atoms in a compound or the number of atoms in a polyatomic ion.
The number of protons in each nucleus of an atom of the element.
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 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.
