An isotope has either more or fewer neutrons than a stable atom, and neutrons are part of the nucleus.

What relationship exist between the mass number of an element and the isotopes of that element?

Each isotope of the same element has a specific mass number, which is the sum of the protons and neutrons in the nucleus.


What describes the relationship between the nucleus and the electron cloud of an atom nucleus?

There is a relationship of attraction.


Do isotopes have a nucleus?

Yes. Isotopes are simply normal elements with a different number of constituent neutrons in their nucleus. All isotopes have a nucleus with an identical number of protons to its element.


Why is it difficult for a chemist to distinquish between isotopes?

The basic reason that it is difficult for the chemist to distinguish between isotopes is that all the isotopes of a given element have the same chemistry. They all behave the same way chemically because the only difference between these isotopes is the number of neutrons in the nucleus of these atoms. And the number of neutrons in the nucleus doesn't really affect the chemistry of an atom of a given element.


What is the relationship between a nuetron and an isotope?

Isotopes of an element has different number of neutrons.


What is a similarity and a difference between isotopes of an element?

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).


The main difference between isotopes of the same element has to dowith the number of?

The main difference between isotopes of the same element is the number of neutrons in the nucleus. Isotopes have the same number of protons and electrons but different numbers of neutrons, which affects their atomic mass.


Isotopes which have unstable nucleus and break down at a constant rate over time?

radioactive isotopes! :)


What is the relationship and sequence between nucleus?

This question does not make sense.


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.


How does the mass of a nucleus differ from the mass of an electron?

There is no simple answer.The mass of a nucleus depends on the number of neutrons and protons in the nucleus. The number of protons in the nucleus depends on the element. Moreover, the number of neutrons can vary between isotopes of the same element.
