When the number of neutrons changes, the Atomic Mass will change.
What else can I help you with?
What is the gram atomic mass?
The gram atomic mass, also known as molar mass, is the mass of one mole of an element or a compound in grams. It is numerically equal to the atomic or molecular weight of the substance in atomic mass units.
How is the atomic mass number of a nucleus changed by alpha decay or by beta decay or by gamma decay?
The mass does not change much. The Atomic number will increase though.
The mass of an atom usually expressed in atomic mass units is its?
Atomic mass
What is the atomic mass of silver?
The atomic mass (or weight) of silver is 107.8682 amu (atomic mass units)
What is the atomic mass of aluminum?
The atomic mass number of aluminum is 27. The atomic mass of aluminum is 26.98115386
Did Dmitri Mendeleev organize elements by atomic numbers or atomic mass?
At first, he did it by atomic mass, but that didn't quite work out right, so he changed it to atomic number.
What is the gram atomic mass?
The gram atomic mass, also known as molar mass, is the mass of one mole of an element or a compound in grams. It is numerically equal to the atomic or molecular weight of the substance in atomic mass units.
What can you infer about two substances that have the same atomic number but different atomic mass what term would you use to classify the substance?
They are isotopes. They are the same element with a different amount of nuetrons, which can be determined depending upon the Atomic Mass and the atomic number, which results in the changed atomic mass.
How is the atomic mass number of a nucleus changed by alpha decay or by beta decay or by gamma decay?
The mass does not change much. The Atomic number will increase though.
What is relative atomic mass and atomic mass amu?
The relative atomic mass was first proposed by John Dalton in 1803. According to it, the mass of an atom was expressed relative to the mass of one 1H atom. The unit was later changed to 1/16 of the mass of an oxygen atom. However, this measure was discarded when 17O and 18O were discovered. In 1961 the basic unit was changed (once again) to 1/12 of the mass of a 12C atom. The mass of any atom or molecule is measured in atomic mass units (AMU) and the units is defined as 1/12 the mass of a 12Carbon atom.

How did mendellev design the periodic table?
Mendeleev designed the periodic table by increasing atomic mass. But it was later changed to increasing atomic number.
What is bigger the atomic mass or atomic number?
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
What is the atomic mass-?
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
