Mendelevium 256 has 155 neutrons and mendelevium 258 has 157 neutrons.
As they are isotopes, they've different number of neutrons.
These isotopes have a different number of neutrons.An isomer C-12m doesn't exist; the isotope is C-12.
The density of platinumi s 21,45 g/cm3. The difference in density between isotopes is not significant.
There r no differences but in sm elements the difference can b of radioactivity like in calcium(ca).
They are called isotopes and the difference between different isotopes of one type of element is the amount of neutrons each have.
They are the isotopes. Because of the difference in the number of neutrons by 2 they have been named that way.
The number of neutrons is equal to the atomic mass of an isotope minus the atomic number (or the protons number) of the element. The atomic number of mendelevium is 101 and Md has isotopes with atomic masses between 245 and 260.
pigs and farts
Different numbers of neutrons, e.g. deuterium and tritium are isotopes of hydrogen.
Please see the link.
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.
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.
