Mass number: sum of protons and electrons in the nucleus of an isotope.
Atomic weight: mass of a chemical element expressed in unified Atomic Mass units.
What else can I help you with?
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
Is the mass and atomic mass the same?
No. The atomic weight is the number on the Periodic Table and is a weighted average of the atomic masses.
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.
What is the same about a atomie mass and atomie 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.
Does atomic number and atomic mass mean the same thing?
atomic mass and mass number are differernt because atomic mass mean mass of whole atom which mean mass of proton,neutron and electron while mass number is number of proton and neutron only.zahid ullah paf college risalpur
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 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.
Has a mass about the same as a proton's?
The atomic mass doesn't equal to the number of protons. The number of protons plus the number of neutrons equal to the atomic weight... DAI BI!
What is the same in isotopes?
isotopes always have the same? mass # & atomic #, or atomic # and atomic weight, or atomic # but different mass #'s
What is the Mass number in beryllium?
The atomic mass is the same as the atomic weight therefore it is 9.01218. Beryllium is a non metal element. Atomic mass of it is 9.01. The atomic mass number, which is distinct from the atomic mass and the atomic weight, is 9.
How can you calculate the number of neutrons N in an atom?
equal to number of protons
What is the atomic mass number for nitrogen?
The atomic weight is14.00674
