Nobelium, with the chemical symbol No, is the chemical element with the atomic number 102.
Nobelium is an artificial chemical element, atomic number 102.
Nobelium has 102 protons and 102 electrons, as the number of protons is equal to the atomic number, and in a neutral atom, the number of protons is equal to the number of electrons.
The atomic mass of nobelium is approximately 259.1 atomic mass units.
The atomic mass of nobelium reported as a whole number is usually the average atomic mass of its isotopes, taking into account the natural abundance of each isotope. Since this average is calculated from the weighted average of the isotopes' masses, the result often appears as a whole number.
There are two elements under the atomic number 101 that have names ending in -ium: mendelevium (Md) and nobelium (No). Mendelevium is named after Dmitri Mendeleev, while nobelium is named in honor of Alfred Nobel.
The atomic number of nobelium is 102.
Nobelium is an artificial chemical element, atomic number 102.
Nobelium (No)
Nobelium has 102 protons and 102 electrons, as the number of protons is equal to the atomic number, and in a neutral atom, the number of protons is equal to the number of electrons.
157; you figure that out by taking the atomic mass (259) and subtract it by the # of protons (102) and the answer is the # of neutrons. ( the atomic #, # of protons, and # of electrons are always the same # 102 ). But each isotope of nobelium has a different number of neutrons, depending on the atomic mass.
