The atomic number is the number of protons. The Atomic Mass number is the the sum of the numbers of neutrons and protons combined, in this instance, 11.
Isotopes of the same element have the same number of protons and electrons, but varied numbers of 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.
Not; the number of protons in isotopes is identical; only the number of neutrons is different.
The mass number is the average atomic mass of all the isotopes that are found in nature.
Isotopes and nuclei are both related to atoms. Isotopes are atoms of the same element with different numbers of neutrons in their nuclei. The nucleus is the central part of an atom that contains protons and neutrons.
NO they have same number of protons. But neutrons are 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.
Atoms that vary in the number of neutrons found in their nuclei are called isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons, which can lead to variations in their atomic mass.
Atoms containing the same number of protons but different numbers of neutrons are called isotopes. Isotopes have the same atomic number (number of protons) but differ in atomic mass due to the varying number of neutrons.
Uranium isotopes have 92 protons and electrons; the number of neutrons is different for each isotope.Number of neutrons = Mass number - Number of protons
An atom's mass number is the total number of protons and neutrons in its nucleus. It is used to identify isotopes of an element since isotopes of the same element have the same number of protons but different numbers of neutrons.
