The atomic radius is calculated by spctroscopic or X-ray methods.
The element nickel (Ni) has an atomic radius of 124 picometers.
The atomic radius of bromine is lower.
Barium has a larger atomic radius than tin.
Helium usually is listed with the smallest atomic radius when calculated. Hydrogen however has a smaller van der Waals radius
Platinum is a metal element. Atomic mass of it is 195.08.
It is helium that has the smallest atomic radius. Use the link below to see a list of elements arranged by atomic radius.
Element b would have a larger atomic radius than element c as you move down a group on the periodic table, the atomic radius tends to increase. This is because each successive element has an additional electron shell, leading to an increase in size.
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.
65 picometers.
Yes, selenium is bigger than polonium. Selenium is a nonmetal element with an atomic number of 34 and a larger atomic radius compared to polonium, which is a metalloid element with an atomic number of 84 and a smaller atomic radius.
The atomic radius, is the measured size of the atoms of a chemical element. Usually this is the typical distance between the nucleus and the boundary of the surrounding electrons.
Bromine has the largest atomic radius among fluorine, chlorine, and bromine. Atomic radius increases down a group on the periodic table, so bromine, located at the bottom, has the largest atomic radius of the three elements.
