Nobelium has 102 protons.
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.
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.
Nobelium is a radioactive, artificial chemical element.
Nobelium is an artificial chemical element, atomic number 102.
Nobelium is an element, so it is a pure substance made of nobelium.
Nobelium is an artificial element.
As all other chemical elements nobelium has protons, neutrons and electrons inside.
Nobelium is an artificial element; it is prepared only by nuclear reactions in accelerators.
Nobelium is an artificial element.
Nobelium is an artificial chemical element.
The Synthetic Element Nobelium was named for Him.
As all other chemical elements nobelium atom contain protons, neutrons and electrons.
