Depends, what do you mean "change"? Atomic Mass "changes" whenever something undergoes decay or breaks apart. In this respect, atomic mass is not exactly conserved either. Rest mass gets converted to energy; e=mc^2, meaning energy is equal to mass times the speed of light squared. This energy is usually the kinetic energy of the particle that gets dislocated from the original atom.

Does atomic mass has a positive change?

No. Atomic mass is a measure of mass, not charge.


What type of nuclear decay results in the atomic number increasing by one with no change in mass?

Beta- decay result in an increase of atomic number by one, with no resulting change in the atomic mass number.There is a change in mass, since an electron and an electron anti-neutrino is emitted, and also because the neutron changes into a proton, but the atomic mass number, per se, does not change.


Does the element change when the atomic mass changes?

No, the element remains the same even when the atomic mass changes. Atomic mass is determined by the number of protons and neutrons in the nucleus of an atom, but changing the number of neutrons does not change the identity of the element.


What changes in atomic number and mass number occur in beta emission?

Electron (beta minus) decay: the atomic mass remain approx. constant, the atomic number will be greater with 1 Positron (beta plus) and electron capture decay: the atomic mass remain approx. constant, the atomic number decrease with 1 Double beta decay: the atomic mass remain approx. constant, the atomic number will be greater with 2


When the atomic mass changes does the element change also?

no


How is the atomic mass changed?

When the number of neutrons changes, the atomic mass will change.


How does the atomic mass change when a proton is added to its nucleus?

Since the atomic mass consists of protons and neutrons, adding a proton would add one unit to the atomic massguessing that the number of neutrons doesn't change.


What can be added or taken away from an atom to change the atomic mass?

The atomic mass of an atom can be changed by adding or removing subatomic particles. By adding or removing protons, neutrons, or electrons, the atomic mass will be altered. Changing the number of protons will change the element, while changing the number of neutrons will create isotopes of the same element.


How did later chemists change Mendeleevs periodic table?

They used atomic number instead of Atomic Mass to organize the elements


Can the atomic mass of a particular element ever change?

yes


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 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
