The atomic number of carbon is 6.
Here's how you can find it:
-
Periodic Table: The most straightforward method is to consult the periodic table of elements. Elements are arranged in order of increasing atomic number. Carbon (C) is located in Group 14 (formerly Group IVA) and Period 2, and its atomic number is clearly displayed as 6.
-
Definition of Atomic Number: The atomic number of an element represents the number of protons in the nucleus of each atom of that element. Since carbon has 6 protons in its nucleus, its atomic number is 6. This number uniquely identifies carbon as carbon. An atom with 7 protons would be nitrogen, not carbon.
-
Understanding Isotopes: While carbon has different isotopes (e.g., Carbon-12, Carbon-13, Carbon-14), each isotope still has 6 protons. Isotopes differ in the number of neutrons, affecting the atomic mass but not the atomic number.
-
Reference Materials: Textbooks, scientific publications, and reputable online resources (such as chemistry websites or encyclopedias) will always provide the atomic number of carbon as 6.
In summary, the atomic number of carbon is a fundamental property of the element, easily found on the periodic table and defined by the number of protons in its nucleus.
