Atomic Mass increases with the ordered placement of the element of the Periodic Table. Conveniently, the number of protons, nuetrons and electrons also increase with numbered order on the table. Every element is assigned a number. This number is equal to the number of protons, nuetrons and electrons. I believe it's the nuetrons that make up the mass of the element, but not sure!
All isotopes of an element have the same number of protons in their nucleus. This is what defines them as being the same chemical element. The number of protons determines the element's atomic number.
The isotopes of an element have the same number of protons, but different numbers of neutrons.
An element is defined by the number of protons, so this cannot vary. Isotopes of a particular element are different in the number of neutrons within the atoms. These isotopes are said to be comparatively "lighter" or "heavier" than other isotopes based on the total of protons and neutrons (atomic mass).
The answer you are looking for is "isotopes" HOWEVER, please note you CAN NOT HAVE 2 elements with the same number of PROTONS. This is because the number of protons DEFINES an element. Isotopes are the SAME element but with differing numbers of neutrons.
All isotopes of an element have the same number of protons in the atomic nucleus, which is its atomic number on the periodic table. All isotopes of an element contain different numbers of neutrons in their atomic nuclei, which causes the isotopes of an element to vary in mass number (protons + neutrons).
This statement is incorrect. Isotopes of an element have the same number of protons but differ in their number of neutrons. Rubidium, specifically, has two stable isotopes: Rb-85 and Rb-87, which both have 37 protons but different numbers of neutrons.
If the number of protons changes so does the element, as the number of protons defines the element.
All isotopes of an element have the same number of protons in their nucleus. This is what defines them as being the same chemical element. The number of protons determines the element's atomic number.
The isotopes of an element have the same number of protons, but different numbers of neutrons.
Isotopes of the same element have the same number of protons and electrons, but varied numbers of neutrons.
An element is defined by the number of protons, so this cannot vary. Isotopes of a particular element are different in the number of neutrons within the atoms. These isotopes are said to be comparatively "lighter" or "heavier" than other isotopes based on the total of protons and neutrons (atomic mass).
Isotopes of an element have the same numbers of protons in the nucleus (and corresponding electrons). It's not so much "can have", as "do have". It's just a different number of neutrons that makes a different isotope.

An isotope has same number of protons but a different number of neutrons as the original element in the atomic nucleus; it has the same atomic number as the element which isn't an isotope, but will have a different mass number. -atomic number

All isotopes of an element have the same number of protons in the atomic nucleus, which is its atomic number on the periodic table. All isotopes of an element contain different numbers of neutrons in their atomic nuclei, which causes the isotopes of an element to vary in mass number (protons + neutrons).
Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons. An example is carbon-12 and carbon-14, which both have six protons but differ in the number of neutrons they possess.
