After IUPAC (2009) the standard atomic weight of mendelevium is [258].
The atomic number of mendelevium is 101.
Mendelevium, with the chemical symbol Md, is the chemical element with the atomic number 101.
Mendelevium has the atomic number 101 (in the Actinides)
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 has 101 protons and electrons.For each isotope the number of neutrons is different.Number of neutrons = Mass number of an isotope -101
Mendelevium has 101 protons and electrons. Number of neutrons = Atomic mass of an isotope - atomic number of mendelevium (101)
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.
The atomic number of mendelevium is 101.
The atomic number of mendelevium is 101.
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.
Mendelevium, with the chemical symbol Md, is the chemical element with the atomic number 101.
The estimated atomic radius of mendelevium is 194 pm.
Mendelevium has the atomic number 101 (in the Actinides)
Mendelevium is a sufficient example for the element with the atomic number 101.
Well, I couldn't get any stable element with mass number of 77. However the closest ones are arsenic with mass number 75 or selenium with mass number 79. Note: All the following elements listed below have isotopes with mass number 77, but are unstable with half life ranging from a few hours to nano seconds: Nickel, Copper, Zinc, Galium, Germanium, Arsenic, Selenium, Bromine, Krypton, Rubidium, Strontium and Yttrium. If you had meant atomic number, then iridium has the atomic number of 77.
It is in 101st element in the Periodic Table.. Md-Mendelevium
Mendelevium is an artificial chemical element, atomic number 101, metal, solid, radioactive, unstable, actinoid.
