What number is used to identify different elements on the periodic table?

atomic number (or number of protons)


How do you identify an atom?

- Atomic number is equal to the number of protons - Atomic number is equal to the number of electrons (in a neutral atom) - Atomic number is the number of a chemical element in the periodic table of Mendeleev


What must the atomic number also identify?

Atomic Number identifies the following:No. of protons (same as the atomic number)No. of electrons (mostly same as no. of protons)Approximate Atomic Mass (No. of neutrons are roughly equal to or near to no. of protons)


What can the atomic number and what things can it identify?

The atomic number is the number of protons in the nucleus of an element. It is what determines what kind of an element it is. When you change the number of protons in the nucleus, you change the type of element.


The atomic number is similar to a fingerprint because?

it is unique for each element and distinguishes one element from another based on the number of protons in the nucleus. Just like how a fingerprint can identify a specific individual, the atomic number can identify a specific element in the periodic table.


What is the atomic number used for?

The atomic number of an element is the number of protons found in the nucleus of an atom. The atomic number is identical to the charge number of the nucleus. For example, the atomic number of Oxygen is 8.


Can you identify an atom without knowing number of neutrons in it?

Yes, and in order to find the Number of Neutrons, subtract Atomic Mass from Number Of Protons, the result will be the Number of Neutrons for that atom *No. Of Neutron=Atomic Mass - Number Of Protons


How does the atomic number identify the atoms of a particular element?

The atomic number of an element is unique to that element. The atomic number is equal to the amount of electrons in one atom of that element. As each element categorically has it's own amount of electrons, you can identify an element from this number.
