Before we tackle isotopes and neutrons, lets talk about protons. The number of protons in an atom determines the elemental identity of the atom. Only that. Now to the question. Atoms of a given element have a specific number of protons in the nucleus, but can have a modest variety of numbers of neutrons in their nuclei. Let's look at hydrogen. Hydrogen is identified by the fact that there is a single proton in the nucleus. Most hydrogen is just that. But some hydrogen has a neutron stuck to the one proton in the nucleus. This creates another "flavor" of hydrogen. It's another isotope of hydrogen. We have the original isotope of hydrogen (with one proton and no neutron) and the isotope with the one proton and one neutron. Now we look at the last and most unusual isotope of hydrogen. It has the one proton and two neutrons. Hydrogen has three isotopes, and each has the same number of protons (each isotope is hydrogen) and each has a different number of neutrons: zero, one and two. Heavier elements have varying numbers of neutrons in combinations with there protons. This creates a number of different isotopes for each and every element. It is the variable numbers of neutrons that can hang out with the protons in a given element's nucleus that give rise to the different isotopes of that element. Our friends at Wikipedia have some details. A link is provided.

How do two isotopes of an element are similar?

They have the same number of protons in the nucleus and same number of electrons surrounding the nucleus.


What atoms has different masses but the same atomic number?

Isotopes of an element have different masses but the same atomic number. Isotopes have the same number of protons and electrons but different numbers of neutrons in their nuclei.


What is the number of electrons in bromine-82?

Bromine-82 has 36 electrons since bromine has an atomic number of 35, which corresponds to the number of electrons in a neutral atom. The number of electrons remains the same in different isotopes of an element.


What are atoms called if they have the same number of protons but different number of neutrons?

An atom of an element having the same number of protons (as well as electrons) but a different number of neutrons is known as an isotope. Isotopes are often used in the nuclear power industry. An example of an industry is "heavy water" or Deuterium Oxide. It is water but with and isotope of hydrogen that has 2 extra neutrons. The isotope is called Deuterium, and heavy water is also sometimes known as D2O.


Why do the two isotopes of chlorine have the same chemical properties?

Oh, dude, it's like this - isotopes of an element have the same number of protons and electrons, so they behave chemically the same way. The number of neutrons might be different, but that's like saying you have different hair colors - doesn't change who you are on the inside, right? So yeah, chlorine isotopes are basically twins in the chemistry world.

How is isotopes related to number of electrons?

An isotope is not really related to the number of electrons, but rather it is determined by the number of neutrons.


Do isotopes differ by number of electrons?

Isotopes differ by the number of protons.


Do isotopes contain more electrons than other Atoms?

No, they contain different number of electrons. Isotopes differ in their number of neutrons.


How do the number of electrons compare in two isotopes in an element?

In a neutral atom, the number of electrons equals the number of protons. Isotopes of the same element also have the same number of electrons and the electronic structure.


Do isotopes exist because atoms of the same element can have different numbers of electrons?

Isotopes have the same number of protons an electrons; the number of neutrons is different.


What are the number of electrons in each of the three isotopes of oxygen?

eight electrons


Which is not true all isotopes of an element have the same number of electrons?

All neutral atoms of an element, including any of its isotopes, always do have the same number of electrons. The existence of isotopes has nothing to do with the number of electrons in an atom. Instead, the number of neutrons varies between isotopes of the same element. The number of electrons varies from that of a neutral atom only if an ion of the element is formed.


Do the atomic number of isotopes differ?

No. Isotopes have the same atomic number, protons and electrons. They have different neutrons.


Would isotopes of the same element have the same number of electrons?

Yea because isotopes only differ in their # of neutrons, not electrons


How much do isotopes that share an element differ in the number?

Isotopes have a different number of neutrons but the number of protons and electrons is the same.


How many electrons are their in uranium - 235?

92 electrons - the number of electrons is the same in all the isotopes of uranium. Number of electrons = Number of protons = Atomic number


Why isotopes of an element show identical chemical properties?

The number of electrons in isotopes is identical.
