Sorry if I'm wrong but it is it in transition metals
Yes, francium has the largest atomic radius of any element on the periodic table. This is due to its position at the bottom of the alkali metal group, with only one valence electron and a high number of energy levels, resulting in a larger atomic size.
Cesium, which is in Group 1 of the periodic table, has the largest atoms. This is because as you move down a group, the atomic size generally increases due to the addition of more electron shells.
Atomic size increases down a group as the energy level (or shell) increases. So Astatine will have the largest size (radius) in group 17
Germanium is the largest of the two. It has a larger atomic mass.
Down the group, size increases. Because number of shells increases.
The atomic radius decreases.
Atomic size increase down the group and decreases across the period.
Magnesium (Mg) is the largest atom among sulfur (S), sodium (Na), chlorine (Cl), and magnesium (Mg). This is because the size of an atom increases as you move down a group in the periodic table. Magnesium is located below the other elements in the periodic table, making it the largest atom among these options.
Metallic elements make up about 70% of the Periodic Table of Elements.
Sodium has the largest atomic size in the third period.
In the periodic table, elements that are relatively larger in size appear in the bottom left corner. This is because the size of an atom increases as you move down a group due to the addition of energy levels.
Fr (Francium) has the largest atomic size compared to Li (Lithium) because Francium is located at the bottom of group 1 on the periodic table, which means it has more energy levels and electron shells compared to Lithium, hence larger atomic size.
