How To Find Element Atomic Number, Element Name & Symbol


The atomic number (symbol Z) is also called the proton number of a chemical element. It is the total number of protons that found in the nucleus of an atom. It is similar to the charge number of the nucleus. Through atomic number one can uniquely identify a chemical element. The atomic number is also equal to the number of electrons in, sodium, magnesium uncharged atom.

Atomic Number of Elements from 1 to 30

In the picture below we are going to provide the atomic number of the element 1 to 30 that are hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, aluminum, silicon, phosphorus, sulfur, chlorine, argon, potassium, calcium, scandium, Titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper and zinc.

Elements with Atomic Number and Mass

Atomic mass is the total number of proton, neutron, and electron present in an atom of the element. The mass of an atom of the element is expressed in atomic mass units.

Elements with Atomic Number and Mass

It is roughly equal to the number of protons and neutrons in the atom. It is also the average number allowing for the relative abundances of different isotopes.

How to Find an Element’s Atomic Number

Atomic number = number of protons, and mass-number = number of protons + number of the neutron. You can check the atomic number of the element in the picture below.
