Samarium has a calculated atomic radius of 238 pm.
The alkali metal with an atomic radius of 238 pm is potassium (K). Its large atomic radius is due to the added electron shells compared to other alkali metals in the same period.
The atomic radius of iridium is approximately 136 picometers (pm).
Do you think at atomic radius ? Zr calculated atomic radius: 206 pm, Hf calculated atomic radius: 208 pm. Or atomic mass? Zr: 91,224, Hf: 178,49.
The atomic radius of selenium can be estimated to be approximately between 116 pm and 118 pm based on the trends in atomic radii going down a group in the periodic table. This is because atomic radius generally increases as you move down a group, so selenium's atomic radius would be smaller than arsenic's and germanium's.
Only the atomic radius is equivalent - 128 pm.
The alkali metal with an atomic radius of 238 pm is potassium (K). Its large atomic radius is due to the added electron shells compared to other alkali metals in the same period.
Platinum is a metal element. Atomic mass of it is 195.08.
The element with an atomic radius of 97 pm is Francium (Fr). Francium has a large atomic radius due to its location in the alkali metal group, which generally have larger atomic radii.
Gallium has an atomic radius of 135 picometers.
The atomic radius of copper is about 128 picometers (pm).
The atomic radius of Xenon is about 108 picometers (pm).
The atomic radius of iridium is approximately 136 picometers (pm).
Gallium is a non metal element. Atomic mass of it is 70.
The atomic radius of cadmium is approximately 151 picometers (pm).
The atomic radius of protactinium is 180 pm.
The empirical atomic radius of promethium is 183 pm.
The empirical atomic radius of polonium is 168 pm.
