What is the gram atomic mass?
the relative atomic masses of compounds changed into g grams called the gram atomic mass of that element.for example mass of hydrogen 1.008 gram etc
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 the difference between atomic mass and atomic mass unit?
The atomic mass unit is used to express the measure of the atomic mass.
Can the atomic number of an particular element ever change?
No, the atomic number of an element can't change. Because, we can identify an element by its atomic number and atomic mass. and hence they have been arranged in the periodic table on the basis of their mass number and atomic mass so , it couldn't be changed. Every element has a fixed atomic number..
What is the atomic mass of magnessium?
The atomic mass of magnesium is approximately 24.305 atomic mass units (amu).
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 relative atomic masses of compounds changed into g grams called the gram atomic mass of that element.for example mass of hydrogen 1.008 gram etc
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.

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.
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.
The equation of atomic mass?
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
What is the atomic mass of colbat?
Cobalt is an atomic mass of 58.93 atomic mass units
