What is a man-made element with one-hundred-forty-eight neutrons?
Many isotopes have 148 neutrons; example: mendelevium -249.
How many protons and neutrons does Mendelevium have?
Mendelevium is element 101, so it has 101 protons. Several isotopes are known, with atomic masses ranging from 245 to 262, hence from 144 to 161 neutrons. The most stable, with half-lives measured in weeks rather than hours or less, have atomic mass 258 and 260, thus 157 and 159 neutrons.
How many electrons and neutrons in mendelevium have?
Mendelevium has 101 protons and electrons.For each isotope the number of neutrons is different.Number of neutrons = Mass number of an isotope -101
Mendelevium -256 and mendelevium-258 what is the difference between the nuclei of these two isotopes?
Mendelevium 256 has 155 neutrons and mendelevium 258 has 157 neutrons.
How many protons nuetrons and electrons does mendelevium have?
Mendelevium has 101 protons and electrons.For each isotope the number of neutrons is different.Number of neutrons = Mass number of an isotope -101
What is the number of neutrons in a single atom of mendelevium?
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.
What is the element mendelevium atomic structure?
The atom of the isotope Md-256 has 101 protons, 101 electrons and 155 neutrons.
