The three isotopes of an element: carbon.
The three isotopes you mentioned, 6/2 C, 6/3 C, and 6/4 C, represent different carbon isotopes.
Isotopes of an element have the same number of protons (which defines the element) but differ in the number of neutrons.
Carbon, with the atomic number 6, typically has six protons.
6/2 C: This isotope has 6 protons and 2 neutrons. It is known as carbon-12 (C-12) and is the most abundant and stable isotope of carbon, constituting about 98.9% of natural carbon.
6/3 C: This isotope has 6 protons and 3 neutrons. It is called carbon-13 (C-13).
Although it is less abundant than C-12, it still occurs naturally and is stable. C-13 is often used in nuclear magnetic resonance (NMR) spectroscopy to study the structure of organic compounds.
6/4 C: This isotope has 6 protons and 4 neutrons. It is referred to as carbon-14 (C-14) and is radioactive.
C-14 is formed in the atmosphere through interactions with cosmic rays and is used in radiocarbon dating to determine the age of organic materials.
Carbon-12 (6/2 C), carbon-13 (6/3 C), and carbon-14 (6/4 C) are three isotopes of carbon, each with a distinct number of neutrons and unique properties.
The combination of stable and radioactive isotopes makes carbon a versatile element with applications in various scientific fields.
