No, the mass number is not the same as the Atomic Mass. The mass number is the total number of protons and neutrons in an atom's nucleus, while the atomic mass is the average mass of all the isotopes of an element, taking into account their abundance.

What happen to atomic number and mass number of nucleus when it emits alpha particle electron and proton?
It's been awhile for me, but this is how I remember it. It is not convenient for me to look it up right at the moment, so you may want to verify this. Emitting an alpha particle (2 proton 2 neutron), atomic number would decrease by 2 and atomic mass decreases by 4.Electron emission means a neutron turns into a proton and electron, but the electron shoots out. The atomic number increases by 1 and atomic mass stays the same. Proton emission, well it loses a proton. So the atomic number decreases and mass decreases.
What is the number of neutrons in an atom affects the atomic what?
The number of neutrons in an atom can affect the atomic mass of an atom.
If an atom has 35 electrons and its mass number is 80 calculate the number of protons?
In a neutral atom, the number of electrons will be the same as the number of protons. This is because one positive proton will cancel out one negative electron; therefore, if the atom is neutral, it must have the same number of protons and electrons.The number of protons is also the same as the atomic number. For this example, Bromine, with the atomic number of 35, has 35 protons.Bromine:Atomic number- 35Number of protons- 35Number of electrons- 35The mass number is the sum of the atomic number (or number of protons/electrons) and the neutrons. For this example, we know the atomic number (35) + # neutrons = mass number (80). To figure out the number of neutrons, take the mass number and subtract the number of electrons/protons/atomic number. Mass number (80) - atomic number (35) = neutrons (45).
How do you calculate neutrons for elements in the periodic table?
them mass number of an element is the total amount of nuetrons and protons in the element , and the atomic number is the amount of protons ( and electrons) in the element simply subtract the atomic number from the mass number and you'll have the number of neutrons in the element hope this helped x
What term best describes the sum of the number of protons and neutrons in an atom?
Atomic mass or mass number.
Do isotopes have the same atomic number and the same atomic mass?
No: They have the same atomic number but not the same atomic mass.
Is the atomic number and atomic mass the same?
No, the atomic number is the amount of protons it has and the weight is its mass
How atomic number better than atomic mass?
No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
Is the atomic number the same as atomic mass?
No.
Is atomic mass and molar mass similar and mass number of particles the same?
Atomic mass and molar mass are similar concepts but not the same. Atomic mass refers to the average mass of an atom of an element, while molar mass is the mass of one mole of a substance. The mass number of particles can be the same in certain cases, such as isotopes of the same element which have the same number of protons and different numbers of neutrons.
What is the atom with same atomic number but different mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Is atomic mass and atomic number the same thing?
No, atomic mass and atomic number are not the same thing. Atomic mass represents the average mass of an atom of an element, which includes the mass of protons, neutrons, and electrons. Atomic number, on the other hand, represents the number of protons in the nucleus of an atom, which also determines the element's identity on the periodic table.
What is the difference between isobar and isotope?
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
What do two different neutral isotopes of the same element have in common nuclear number atomic mass nuclear mass atomic number?
The atomic number is the same for all isotopes.
What is the atomic mass the same as?
The Atomic Mass is equal to the number of protons and electrons that an element has.
Do carbon and oxygen have the same atomic mass?
They don't contain the same number of particles because some particles are more dense than others making one atom and another atom the same mass but not have the same number of particles.
What is silvers atomic mass?
actually the atomic mass is the same as the amount of protons so if you want to be lazy here are the atomic number (in which is 47 also the same as the atomic mass) and the atomic mass 47, and the number of protons 47.
