Can atoms of two different elements have the same atomic number and could they have the same mass number?
The atomic number, or Proton number, defines which element it is. So by definition, two different elements must have a different atomic number, or else they'd be the same element. Atomic mass is the number of protons + neutrons in the element's nucleus. Since the number of neutrons in the nucleus can vary, even within a single element (as isotopes) it is possible to have one isotope of one element sharing an atomic mass with an isotope of another element.
What atoms of two different elements must have different?
Atoms of different elements must have different numbers of protons in their nuclei, which defines the atomic number of each element. For example, hydrogen has one proton, while helium has two. This difference in proton count leads to variations in chemical properties and behavior, distinguishing one element from another. Additionally, the number of neutrons can vary within atoms of the same element, resulting in different isotopes, but the defining characteristic remains the number of protons.
Does atomic mass stay the same?
The atomic mass of a radioactive atoms is changed during the radioactive decay (alpha decay, neutron decay, proton decay, double proton decay), spontaneous or artificial fission, nuclear reactions.
Do all elements in the same group have the same atomic mass?
No. Atoms of the same element can have different masses as the number of neutrons can vary. Atoms of the same element but with different masses are called isotopes.
Atoms of different elements are what?
Atoms of different elements are characterized by the number of protons they contain in their nucleus, which determines the atomic number and identity of the element. The arrangement and number of electrons in the electron cloud surrounding the nucleus also vary among elements. Additionally, different elements have unique chemical properties based on how their atoms interact with one another.
How can Atoms vary?
Atoms and elements can vary in many ways. Atoms mainly vary by having different numbers of protons, electrons, and neutrons. The count of protons makes up an elements mass number.

Can an atom of two different elements have the same mass number?
Yes. The mass number is basic to the different elements, even more useful than the atomic number. (Unless it is an isotope. Isotopes have a different amount of neutrons than the basic element atom which makes a difference in mass number too. So, a difference in mass numbers doesn't always mean it is a different element.)
In the electron charge to mass experiment if the electron is replaced by a proton or neutron would the charge to mass ratio value still be the same why or why not?
Compared to the (charge/mass) ratio of the electron:-- The (charge/mass) ratio of the proton is much smaller; although the proton charge is equal to the electron charge, the proton mass is much larger, by a factor of more than 1,800.-- The (charge/mass) ratio of the neutron is zero, because the neutron charge is zero.

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.
Why is atomic number better than atomic mass for organizing the elements in the periodic table?
Atomic number is a unique number for each element. No two elements have the same atomic number. Atomic number is also the number of protons in the nuclei of the atoms of any given atom. Atomic mass, however, is the number of protons, neutrons and electrons. The number of neutrons can vary with different isotopes of the same element, this means that atomic mass can vary with different isotopes. So atomic number does not vary, but atomic mass does, so it is more logical to use atomic number to organize the elements. In addition, when the elements are arranged according to atomic number into seven rows and 18 columns, it becomes evident that there are certain trends that occur across the periods, and that elements in the same group have similar properties.
how isotopes can have different masses and still be the same element?
For the same element the number of protons and electrons remains unaltered. Howerm for that same element the number of neutrons can vary., leading to different atomic masses. Taking hydrogen as an example. It has three isotopes. #1 ; protium ; 1 proton , 0 neutrons (Atomic Mass ; 1 + 0 = 1 ) #2 ; deuterium ; 1 proton , 1 neutron ( Atomic mass ; 1 + 1 = 2) #3 ; tritium ; 1 proton, 2 neutrons ( Atomic Mass ; 1 + 2 = 3) Notice for each isotope of hydrogen there is only ONE proton. However, for each different isotope of hydrogen there is a different number of neutrons. The Atomic Mass is the sum of the protons and neutrons). #4 ; Helium(He) ; 2 protons, 2 neutrons ( atomic mass 2 + 2 = 4 ). For comparison helium has 2(TWO) protons and 2 neutrons, but it is an entirely different element, because it has a different number of protons.
How do you atomic masses vary throughout the periodic table of elements?
Each element has its own atomic mass.
