How do I find the Atoms?

So, if you are given the mass of an element, you use the periodic table to find its molar mass, and multiply the given mass by the reciprocal of the molar mass. This is Mass → Moles . Once you have moles, multiply by Avogadro's number to calculate the number of atoms. This is Moles → Atoms .

Explanation:

The electron mass has the smallest mass between the basic particles inside the atoms

Inside the atom consists of a nucleus containing 3 basic particles namely protons and neutrons, while electrons move around the nucleus.

The charge of 1 proton is equal to a charge of 1 electron, but the sign is different.

The proton is positively charged (+1), the electron is negatively charged (-1). and neutrons not charged (neutral)

For a charge of 1 electron = e = 1.66.10⁻¹⁹ coulomb

Whereas the neutron charge = 0

The mass number is not the same as the atomic mass. The mass number is the number of protons and neutrons in one atom. While the atomic mass is a number that expresses the mass of one atom.

Atomic mass is expressed in special units, namely atomic mass unit because the atomic mass is very small if expressed in units of grams or milligrams

This atomic unit uses the standard atomic mass, that is, the C-12 isotope

1 atom C-12 = 12 atomic mass unit

1 atomic mass unit = 1/12 x mass 1 atom C-12

The mass of 1 proton is equal to the mass of 1 neutron, equal to 1 atomic mass unit and electrons have a mass smaller than both.

The proton mass is considered to be equal to 1 atomic mass unit and a neutron which has a slightly larger mass is also considered to be equal to 1 atomic mass unit

1 unit of atomic mass = 1.6726.10⁻²⁴

So the electron mass has the smallest mass between the basic particles inside the atoms

The electrons themselves were first discovered by JJ Thompson through experiments with vacuum tubes, while the electron charge was discovered by Robert Milikan.

Proton discovered Goldstein through a cathode  ray experiment and Neutron by James Chadwick
