What is the difference between atomic mass and atomic mass unit?

Atomic weight is a weighted average of the mass of all the atoms of an element, based on the abundance of isotopes. Both atomic mass and atomic weight rely on the atomic mass unit (amu), which is 1/12th the mass of an atom of carbon-12 in its ​ground state.

What is the difference between the mass number and the atomic number of an atom?

The major difference between atomic number and mass number is that the atomic number states the number of protons present in an atom whereas, the mass number indicates the total of the number of protons and the number neutrons present in an atom.

What is the difference between the mass number and the atomic number of an atom quizlet?

Atomic number is the amount of protons in the nucleus. The mass number is the total number of protons and neutrons.

What is the difference between atom and molecule?

Atom refers to the smallest constituent unit of a chemical element. Molecules refer to a group of two or more atoms that are held together due to chemical bonds.

What is the difference between C 12 and C 13?

Carbon occurs naturally in three isotopes: carbon 12, which has 6 neutrons (plus 6 protons equals 12), carbon 13, which has 7 neutrons, and carbon 14, which has 8 neutrons.

What is the primary difference between 13C and 12C?

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.

What is the difference between the terms atomic mass and atomic weight quizlet?

What is the difference between atomic mass and atomic weight? Atomic mass is the mass of an individual atom, whereas atomic weight is the average (weighted) of the atomic masses of an atom’s naturally occurring isotopes.

What is the difference between atoms that have different atomic numbers?

ISOTOPES AND ATOMIC MASSES For many of the chemical elements there are several known isotopes. 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.

What is difference between particle and atom?

Atoms are small units of matter which contain several particles; we call them subatomic particles. However, the term particle refers to any small object. Therefore, the key difference between atoms and particles is that atoms are small units made of several particles, whereas particles are minute portions of matter.

What is the difference between molecule of compound and molecule of element?

The only difference between a molecule of a compound and a molecule of an element is that in a molecule of an element, all the atoms are the same. For example, in a molecule of water (a compound), there is one oxygen atom and two hydrogen atoms. But in a molecule of oxygen (an element), both of the atoms are oxygen.

What is the difference between C-12 C-13 and C-14?

Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. Carbon occurs naturally in three isotopes: carbon 12, which has 6 neutrons (plus 6 protons equals 12), carbon 13, which has 7 neutrons, and carbon 14, which has 8 neutrons.
