the atomic number is 88
Radium is a non meta element. Atomic number of it is 88.
this elemnt has an atomic number that is double the atomic number of silicon?
Uranium is the first element known to be radioactive. It was discovered by Henri Becquerel in 1896.
The element with an atomic number that is double the atomic number of silicon is germanium, with an atomic number of 32. Silicon has an atomic number of 14.
The element with an atomic number that is double the atomic number of silicon is germanium, with atomic number 32. Silicon has an atomic number of 14.
Radium is a non meta element. Atomic number of it is 88.
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!
Radium. Atomic number 88
The 220 is the atomic MASS, which is the number of protons plus the number of neutrons. 88 is the atomic NUMBER, which is the number of protons only. The "Ra' is the abbreviation for radium, one of the first-detected radioactive elements.
'Ra' stands for Radium in the periodic table. It is a radioactive element with atomic number 88.
Radium has the symbol Ra on the periodic table. It is a highly radioactive element with atomic number 88.
it would be an isotope of Radon, (Radon-230)
The atomic size increases as you move down the Group IIA elements from Be to Ra. This trend is due to the increase in the number of electron shells as you move down the group, leading to greater atomic radius.
The number of protons of an atom is given by its atomic number. Checking the periodic table, we see that the atom with 88 protons is radium. The isotope of radium with 138 neutrons would thus be 226Ra.
Radium 88's atomic weight is 226.0254
22088Ra, like all isotopes of radium, has 88 protons.
Ra stands for Radium on the periodic table. Radium is a radioactive element with atomic number 88 and is commonly used in medicine for some cancer treatments.
