what is the difference between an atom of 12c and 13c?

An isotope is a group whose constituents belong to the same chemical element but have different mass numbers. Carbon has two isotopes: 12C and 13C. Both show the same chemical features because of the same atomic number. But the mass of 13C is larger than that of 12C, because 13C has one more neutron.

C NMR has a number of complications that are not encountered in proton NMR. C NMR is much less sensitive to carbon than 1H NMR is to hydrogen since the major isotope of carbon, the 12C isotope, has a spin quantum number of zero and so is not magnetically active and therefore not detectable by NMR.

The single most important difference between these elements is the number of protons each one contains in its nucleus. The number of protons an atom contains dictates how many electrons it will have. It is the arrangement of electrons around an atom's nucleus that determines that atom's chemical properties.

As adjectives the difference between atomic and subatomic is that atomic is (physics|chemistry) of, or relating to atoms while subatomic is (physics) relating to particles that are constituents of the atom, or are smaller than an atom; such as proton, neutron, electron, etc.

An atom is the smallest amount you can have of an element whereas a molecule is the smallest amount you can have of a compound. A compound is made of atoms.

Carbon has two stable, naturally occurring isotopes. The isotope carbon-12 (12C) forms 98.93% of the carbon on Earth, while carbon-13 (13C) forms the remaining 1.07%. The concentration of 12C is further increased in biological materials because biochemical reactions discriminate against 13C.

But, all atoms are not the same. You know that the number of protons in an atom determines what element you have. For instance hydrogen has one proton, carbon has six. The difference in the number of protons and neutrons in atoms account for many of the different properties of elements.

Explanation: After 1 half-life, 12 of the C-14 would remain. After 2 half-life, 12 of the 12 of the C-14 = 14 of the C-14 would remain.

12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023).

A nucleus of an atom usually contains protons, which are particles with a positive charge, and neutrons, which are particles that are neutrally charged (no charge). On the other hand, in biology, the nucleus of a cell is many times larger than the nucleus of an atom.

Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.

Dividing 12 grams by this incredibly large number of atoms tells us that one carbon-12 atom weighs 1.99 x 10-23 grams. Since a carbon atom weighs 12 AMU, one AMU is equivalent to 1.66 x 10-24 grams. Conversely, one gram is equivalent to 6.022 x 1023 AMU, which is Avogadro's number.

The atomic number of an element is the number of protons in its nucleus. Neutrons are neutral particles having a mass slightly greater than that of the proton. Different isotopes of the same element contain the same number of protons but differing numbers of neutrons.

Elements are the alphabet in the language of molecules. ... In English, you know that “B” is different from “C.” In chemistry, “B” is also different from “C” because boron (B) and carbon (C) are different elements with atoms that have different structures.
