Most elements exhibit isotopes.
Taking hydrogen as an example. It has three isotopes, viz. Protium, Deuterium , and Tritium.
Protium (H-1)contains 1 proton and 1 electrons. It is the commonest isotopes of hydrogen, and is what is commonly thought of as hydrogen.
Deuterium (H-2 /(D))contains 1 proton , 1 electron and 1 neutron. It is sometimes referred to as 'Heavy hydrogen' and is used to make 'Heavy water' for nuclear reactors. etc.,
Tritium (H-3 /(T))contains 1 proton , 1 electron and 2 neutrons. It can be thought of as 'Super heavy hydrogen'. It is the least comment isotope, known only in trace amounts, and is Radio-Active.
Notice all isotopes of hydrogen contain only ONE proton and ONE electron , but the number of neutrons varies.
Other well known isotopes are Carbon-12 / -13/-14 and Chlorine =35/-37 and uranium-235/-236-238
What else can I help you with?
What same mass numbers do isotopes have?
Mass numbers of isotopes are different.
What does isotopes have to do with mass numbers?
isotopes of the same element have different mass number
on what basis mass spectrometer separate isotopes of different element?
The isotopes have different masses.
What are the atoms called then they have the same atomic number but different mass numbers?
They are called as isotopes in which mass number differ by emmision of radiation
What Have different isotopes of the same element?
Isotopes of the same element have different numbers of neutrons and mass.
When atoms of the same element have different mass numbers they are known as?
isotopes
What is it called when you have the same element but different mass number?
They are isotopes of that element, they have different neutron numbers.
Isotopes of carbon have different?
mass nummbers
Why does bromine have different mass numbers?
Different isotopes of bromine have different numbers of neutrons, resulting in different mass numbers. Bromine-79 and bromine-81 are the two most common isotopes of bromine, with mass numbers of 79 and 81, respectively.
Do isotopes of the same element differ in mass number?
isotopes just mean they have a different number of neutrons so if the..Mass number = # of protons + # of neutrons -they will have a different (greater) mass
Atoms of same chemical element that have different atomic mass are known as?
Isotopes. They differ in the number of neutrons in the nucleus.
What is the same in isotopes?
isotopes always have the same? mass # & atomic #, or atomic # and atomic weight, or atomic # but different mass #'s
