From group 17 (7A), fluorine has the lowest atomic radius.
Each column going down the periodic table is an atomic group.
The element in group 1 with the smallest atomic radius is lithium, due to its higher nuclear charge compared to the other elements in the group (such as sodium and potassium). This higher nuclear charge attracts the electrons more strongly, leading to a smaller atomic radius.
Barium has a larger atomic radius than silicon. This is because atoms tend to increase in size as you move down a group in the periodic table due to the addition of more electron shells. Barium is in a lower group than silicon, resulting in a larger atomic radius.
Francium has the largest atomic radius among rubidium, cesium, and francium, as atomic radius generally increases down a group in the periodic table.
The element with the smallest atomic radius among calcium, potassium, scandium, and titanium is titanium. Atomic radius generally decreases from left to right across a period in the periodic table, and titanium is located towards the right side of the group mentioned.

Barium has a radius (not raduis) which is almost twice as large as that of silicon.

idk if this is an answer but this is what i found in my book. atomic raduis increases down a group and decreases across a period
Francium has the largest atomic radius among rubidium, cesium, and francium, as atomic radius generally increases down a group in the periodic table.
In a given period, the element with lowest atomic mass will belong to group 1. It should also be noted that lithium is the metal with the smallest atomic mass.
The element with the smallest atomic radius among calcium, potassium, scandium, and titanium is titanium. Atomic radius generally decreases from left to right across a period in the periodic table, and titanium is located towards the right side of the group mentioned.
The second element in group 1 is beryllium, with an atomic number of 4.
Oxygen is the element having atomic number 8. It is present in group-16.
Element 115 on most modern periodic charts.
The first element is hydrogen.Its atomic no. is 1 and atomic mass is 1.008.
