the atomic number is 88
Radium (Ra) atomic number 88
Strontium(Sr) and Radium(Ra)
this elemnt has an atomic number that is double the atomic number of silicon?
Atomic number 27 : Cobalt Atomic number 28 : Nickel Atomic number 29 : Copper Atomic number 30 : Zinc Atomic number 31 : Gallium
the atomic number 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.
Radium (Ra) atomic number 88
Next element in the periodic table ie Actinium.
Radium 88's atomic weight is 226.0254
The answer is Radium Ra group IIA or atomic number 88
Strontium(Sr) and Radium(Ra)
In the periodic table, Ra stands for the element radium. Radium is a highly radioactive element with atomic number 88. It is in the alkaline earth metal group and is known for its luminescent properties.
For 226Ra, the most common radium, it had 138 neutron. Other isotope scuch as 223, 224, 228Ra will have number of neutron of the stated molecularmass minus its' atomic number.
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.
