No. In fact radium is at the bottom of the Periodic Table where the heaviest elements are. Its atomic number is 88 (compare with carbon, the standard element; atomic number 6)
Radium is a none metal element. atomic number of it is 88.
88
See the link below for the masses of all radium isotopes.
Atomic number of uranium: 92 (the same for all the isotopes) Atomic number of an element = number of protons = number of electrons Atomic mass of the isotopes of uranium: 234, 235, 236, 238, 239, 240, ...., etc. Atomoc mass - Atomic number = Number of neutrons
The atomic number of radium (Ra) is 88.The atomic weight of Ra is 226 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
The atomic number of radium is 88.
Radium is a non metal element. Atomic number of it is 88.
The atomic number is 88 and the atomic mass is 226
Radium is an element, atomic number 88.
Radium is a none metal element. atomic number of it is 88.
Radium is a non meta element. Atomic number of it is 88.
Radium (Ra), atomic number 88, is the most reactive alkaline earth metal. It has the most energy levels of all the alkaline earth metals therefore it's electrons are more easily taken away.
