Different numbers of neutrons, e.g. deuterium and tritium are isotopes of hydrogen.
Number of neutrons in the nucleus.
pigs and farts
mass number
The same numbers of protons and of electrons; the difference between isotopes is in the number of neutrons.
scientists Can tell the difference between two isotopes of the same element because, isotopes of the same elements always have the same number of protons.
No. The only difference between 2 isotopes of the same element is the number of neutrons.
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 are atoms of an element having different number of electrons.
Hello! :D I bet you were expecting an answer huh?
The number of neutrons is different for each isotope.
A similarity between isotopes of an element is that they all have the same number of protons, which means they share the same atomic number and chemical properties. A key difference, however, is that isotopes have varying numbers of neutrons, leading to differences in atomic mass and stability, which can result in some isotopes being radioactive while others are stable.
They are the isotopes. Because of the difference in the number of neutrons by 2 they have been named that way.
