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.
For the representative elements (main group elements), atomic radius generally decreases from left to right across a period. Example: B and Fl: Fl has the smaller atomic radius Li and Be: Be has the smaller atomic radius
This element is tellurium with a covalent atomic radius of 140 pm.
Selenium has the largest atom among phosphorus, sulfur, and selenium because of its larger atomic radius. This is due to selenium having more electron shells and thus a greater distance from the nucleus.
the atomic radius of antimony is 159
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 empirical atomic radius of polonium is 168 pm. The empirical atomic radius of selenium is 120 pm.
For the representative elements (main group elements), atomic radius generally decreases from left to right across a period. Example: B and Fl: Fl has the smaller atomic radius Li and Be: Be has the smaller atomic radius
Among bromine, sulfur, chlorine, and selenium, chlorine has the smallest atomic radius. This is because atomic radius decreases as you move from left to right across a period on the periodic table. Chlorine is located on the right side of the periodic table in the 17th group, which indicates smaller atomic radius.
Calcium has a larger atomic radius. Calcium has an atomic radius of 2.23 Å, while bromine is only 1.12 Å.
This element is tellurium with a covalent atomic radius of 140 pm.
Selenium has the largest atom among phosphorus, sulfur, and selenium because of its larger atomic radius. This is due to selenium having more electron shells and thus a greater distance from the nucleus.
The element with the smallest atomic radius among Ge, Se, Br, and As is Arsenic (As). Atomic size generally decreases across a period from left to right, so the elements in this group progress in order of increasing atomic radius: Germanium (Ge) > Selenium (Se) > Bromine (Br) > Arsenic (As).
Gallium has an atomic radius of 135 picometers.
the atomic radius of antimony is 159
Neodymium (Nd) has an atomic radius of 181 picometers.
Cesium has a larger atomic radius than rubidium. This is because as you move down a group in the periodic table, the atomic radius generally increases due to the addition of more energy levels and electrons.
