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.
Does atomic mass stay the same?
No, atomic mass can vary for different isotopes of an element due to differences in the number of neutrons. The atomic mass on the periodic table represents the weighted average of all the isotopes of that element found in nature.
Do all elements in the same group have the same atomic mass?
No, elements in the same group do not have the same atomic mass. The atomic mass of an element is the weighted average mass of the isotopes of that element, and isotopes can vary within a group.
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.
Why is atomic number better than atomic mass for organizing the elements in the periodic table?
Atomic number is better than atomic mass for organizing elements in the periodic table because it corresponds to the number of protons in an atom's nucleus, which determines its chemical properties. Atomic number also follows a consistent pattern across all elements, unlike atomic mass which can vary depending on isotopes. This makes atomic number a more reliable and fundamental property for organizing and categorizing the elements.
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, atoms of different elements can have the same mass number if they contain different numbers of protons and neutrons. Isotopes of different elements with different atomic number can have the same mass number.
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?
No, the charge to mass ratio value would not be the same if the electron is replaced by a proton or neutron. Protons and neutrons have different charge and mass compared to electrons, so the ratio would vary. The charge to mass ratio is specific to each type of particle.

No, atomic mass can vary for different isotopes of an element due to differences in the number of neutrons. The atomic mass on the periodic table represents the weighted average of all the isotopes of that element found in nature.

What is the atom with same atomic number but different mass number?
Isotopes are atoms with the same number of protons (atomic number) but different numbers of neutrons, resulting in different mass numbers. For example, carbon-12 and carbon-14 are isotopes of carbon.
How do you atomic masses vary throughout the periodic table of elements?
Each element has its own atomic mass.
What are all elements are mixtures of?
An element is composed of atoms all with the same proton number(they are the same type). The only way the atoms in an element can vary is in the number of neutrons they have.
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.
What is a proton and neutron?
A proton is a positively charged subatomic particle found in the nuclei of atoms. The number of protons an element has in its atomic nuclei is its atomic number, and defines the element. A neutron is a subatomic particle that has no charge and is also found in the nucleus of an atom. The number of neutrons in the nuclei of an element can vary. Atoms of the same element that have different numbers of neutrons, giving them different mass numbers, are called isotopes.
