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.

The element that make up a compound and the exact number of atom of each element in a unit of the compound can be shown in a?

The 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.


How do you indentify the elements in a compounds chemical formula?

To identify elements in a compound's chemical formula, look for capital letters. Each capital letter represents a different element. The number of each element in the formula is shown by the subscript next to the element's symbol.


What is the number of atoms of each element?

each element has one atom of the element's name


How are isotopes placed in the periodic table?

Isotopes and their prevalence are not shown on the periodic table. Instead, the atomic weight shown for each element is an average of the atomic weights of all naturally-occurring isotopes (calculated from percentages occurring on Earth).


What law is shown by a balanced equation?

The law of conservation of mass is shown by a balanced chemical equation, which states that matter cannot be created or destroyed in a chemical reaction. This means that the number of atoms of each element must be the same on both sides of the equation.


The number shown on the top part of each of the element squares in a periodic table is the?

This depends on the periodic table but it is either the atomic number (the number of protons) or the atomic mass (the number of protons and neutrons). The integer number will be the atomic number and the larger number will be the atomic mass. The exception is hydrogen which has an atomic number of 1 and an atomic mass of 1 (very close to it).


What is the important of each element?
