They are called as isotopes of the given element.
Two atoms with the same number of protons are not two elements but one element. If they have differing numbers of neutrons, however, they are said to be of different isotopes.
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.
Isotopes of an element have the same number of protons but differing numbers of neutrons in the nucleus.

Isotopes are alternate forms of elements with differing neutron numbers. Isotopes have the same number of protons (and thus the same atomic number), but different numbers of neutrons, leading to variations in atomic mass. Some isotopes are stable, while others are radioactive and undergo decay.
Atoms correspond in that they are all made up of protons, neutrons, and electrons. However, they differ in their mass numbers, which is the sum of protons and neutrons. Atoms of different elements have different mass numbers due to varying numbers of protons and neutrons.
Isotopes of an element have nuclei with the same number of protons (the same atomic number) but different numbers of neutrons Neutrons (:
The number of neutrons in an atom does not identify the element because different isotopes of an element can have the same number of protons (which determines the element) but varying numbers of neutrons. Isotopes of an element have the same number of protons, but differing numbers of neutrons.
Meitnerium has 109 protons and electrons.For each isotope of Mt the number of neutrons is different. Number of neutrons = Mass number of an Mt isotope - 109
Isotopes can exist because atoms of the same element can have different numbers of neutrons, leading to variations in atomic mass. This results in isotopes having the same number of protons but different numbers of neutrons, causing differences in stability and reactivity.
No, atoms do not always have the same number of protons and neutrons. The number of protons determines the element, while the sum of protons and neutrons determines the isotope of an element. Some atoms have equal numbers of protons and neutrons, but others have different numbers.
