Which particles account for the difference between the atomic number and the mass number?
AmberBelle
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 crystal and luster?
Luster is a property of minerals that describes their appearance. A crystal is the structure that minerals possess due to the arrangement of their atomic particles.
What is the difference between solids and liquids based on their atomic?
The difference between solids and liquids at the atomic level is primarily in the degree of freedom of motion that the particles have. In a solid the particles are closely packed together and have very limited movement meaning that the solid maintains a fixed shape. In a liquid the particles have more freedom of movement meaning that the liquid can take the shape of its container. Solids: Particles are closely packed together and have very limited movement the solid maintains a fixed shape. Liquids: Particles have more freedom of movement the liquid can take the shape of its container.
What are the different atomic particles?
The different atomic particles are:protonselectronsneutrons
What is the difference between the atomic number o bromine and the atomic number of chlorine?
Yes
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 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 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 are the different atomic particles?
The different atomic particles are:protonselectronsneutrons
Why are electrons atomic particles?
Because they are particles, and they are part of the atomic structure.
What is the difference between the use of fission as an energy source?
The difference between the use of fission and fusion as an energy source is that in fusion reaction, 2 or more light atomic nuclei fuses to form single heavier nucleus while in fission reaction, heavy atomic nucleus is usually splited into smaller nuclei, other particles and radiation.
What is the difference between the atomic number o bromine and the atomic number of chlorine?
Yes
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.
