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 have the same element but different?

Isotopes of the same element have the same number of protons and electrons, but varied numbers of neutrons.


Which atoms that are same element and have the same number of protons but have different number 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.


Is it true that the number of protons is different for the two isotopes?

Not; the number of protons in isotopes is identical; only the number of neutrons is different.


The mass number of an element is equal to the total number of?

The mass number is the average atomic mass of all the isotopes that are found in nature.


What do isotopes and nucleus have in common?

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.


Does isotopes have insufficent protons?

NO they have same number of protons. But neutrons are different.


What has the same number of protons but a different number of neutrons?

Isotopes.


What are elements with identical number for protons and different number of neutrons called?

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.


What are Atoms that vary in the number of neutrons found in their nuclei called?

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.


What are atoms containing the same numbers of protons and different numbers of neutrons are?

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.


How many electrons protons and neutrons are in uranium?

Uranium isotopes have 92 protons and electrons; the number of neutrons is different for each isotope.Number of neutrons = Mass number - Number of protons


What is an atom's mass number?

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.
