Which particles account for the difference between the atomic number and the mass number?
The answer is that it is neutrons that account for the difference between atomic weight and atomic number. The atomic number is the number of protons or the number of electrons in the atom, since they are normally equal. The atomic weightis the sum of the total number of protons, electrons AND neutrons in the atom. Knowing both the atomic number and the atomic weight of an atom lets you know the number of neutrons in the atom (the isotope). Example: Uranium, Atomic Number 92, Atomic Weight 235. The atomic number tell you that the uranium atom has 92 protons and 92 electrons. The atomic weight tells you that it has a combined total of 235 protons, electrons and neutrons. Since you know from the atomic number that there is a total of 184 protons and electrons in the atom (92 + 92) and from the atomic weight that the total number of protons, electons and neutrons is 235 (92 + 92 + X = 235), you now know that there are 151 neutrons in that uranium atom. The atomic number and atomic weight together tell you that the uranium atom 235 has 92 protons, 92 electons and 151 neutrons.

What is the difference between atomic mass and average atomic mass?
Atomic mass refers to the mass of a single atom of an element, while average atomic mass is the weighted average of the masses of all the isotopes of an element, taking into account their relative abundance in nature.
What is the difference between the mass number and average atomic mass in chemistry?
The mass number is the total number of protons and neutrons in an atom's nucleus, while the average atomic mass is the weighted average of the masses of all isotopes of an element, taking into account their abundance.
How can you account for the difference in mass?
Differences in mass can be attributed to variations in the number of particles or molecules present in a substance. This discrepancy in mass can arise from factors such as atomic weight, density, and composition of the material. The fundamental properties of the elements or compounds involved ultimately determine the mass disparity.
What is the mass defect?
If you add the exact mass of the protons, neutrons, and electrons in an atom you do not get the exact atomic mass of the isotope. The diference is called the mass defect. The difference between the mass of the atomic nucleus and the sum of the masses of the particles within the nucleus is known as the mass defect.
What is the biggest bjump in atomic weights between consecutive elements on the periodic table?
The biggest jump in atomic weights between consecutive elements on the periodic table occurs between uranium (atomic number 92) and neptunium (atomic number 93). Uranium has an atomic weight of approximately 238.03, while neptunium has an atomic weight of approximately 237.05, resulting in a difference of almost 1 atomic mass unit.
What is the difference between news group and irc?
The answer of pi=57.38475734 Is an irrational number due to the sub atomic nature of the particles inside the nucleus.
What are the difference between atomic fission to atomic nuclear?
The difference between atomic fission and atomic nuclear is that they both have something to do with atomic and war. Hope this helps I am kind of in a rush......Smile!
What is the difference between average atomic mass and atomic mass?
Average atomic mass is the weighted average mass of all the isotopes of an element, taking into account their natural abundances. Atomic mass refers to the mass of a single atom of a specific isotope of an element.
What is the difference between atomic mass and average atomic mass?
Atomic mass refers to the mass of a single atom of an element, while average atomic mass is the weighted average of the masses of all the isotopes of an element, taking into account their relative abundance in nature.
What best describes the number of neutrons in an atom?
It is equal to the difference between atomic number and Atomic Mass number. A+
Relation between subatomic particles and atomic mass unit?
protons and neutrons are subatomic particles and adding the two amounts together gives you the atomic mass unit
What is the difference between the atomic number an its atomic mass?
Atomic number is the amount of electrons. Atomic mass is the amount of protons and neutrons.
What is the difference between atomic mass and atomic mass unit?
The atomic mass unit is used to express the measure of the atomic mass.
Why are electrons atomic particles?
Because they are particles, and they are part of the atomic structure.
Explain the difference between atomic mass and average atomic mass?
Atomic mass is the total mass of an atom, which includes the mass of protons, neutrons, and electrons. Average atomic mass, on the other hand, is the weighted average of the masses of the isotopes of an element, taking into account the abundance of each isotope in a sample of the element.

Ionic bond.
