The atomic radius generally increases as you move down a group in the Periodic Table. This is because additional electron shells are added, increasing the distance between the nucleus and the outermost electrons. Conversely, as you move across a period from left to right, the atomic radius decreases due to increased nuclear charge, which pulls the electrons closer to the nucleus.

Which element in each pair has atoms with a larger atomic radius selenium oxygen?
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
Does an atom of fluorine have larger or smaller radius than an atom of iodine?
Smaller
Which has the largest atomic radius Br or Na?
Na has a larger atomic radius than Br. This is because Na is a metal and atoms in metals have larger atomic radii compared to nonmetals like Br, which has a smaller atomic radius due to its higher effective nuclear charge.
How does fluorine's atomic radius compare to oxygen's radius and chlorine's' radius?
Fluorine's atomic radius is smaller than that of oxygen and larger than that of chlorine. This is due to fluorine having more protons than oxygen, which increases the effective nuclear charge and pulls the electrons closer to the nucleus, resulting in a smaller radius. Conversely, chlorine has more electron shells than fluorine, leading to a larger atomic radius. Thus, the order of atomic radius is: chlorine > fluorine > oxygen.
What atom has the larger atomic radius F or Fr?
Fr (Francium) has a larger atomic radius than F (Fluorine) because atomic radius increases as you move down a group in the periodic table. Francium is located at the bottom of the alkali metal group while Fluorine is at the top of the halogen group.
Which element in each pair has atoms with a larger atomic radius selenium oxygen?
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
Does an atom of fluorine have larger or smaller radius than an atom of iodine?
Smaller
Is boron atomicly bigger or smaller than Oxygen?
Boron has a larger atomic radius but a smaller atomic mass.
Does francium or sodium have the smaller atomic radius?
Francium has a larger atomic radius than sodium. Francium is located in the last group of the periodic table, so it has more electron shells than sodium, which results in a larger atomic radius.
Given any two elements within a group is the element with the larger atomic number likely to have a larger or smaller atomic radius than the other element?
The atomic radius decreases across a period from left to right and increases down in a given group. That means that since the lower the element is in a group, the larger the atomic radius will be. The atoms with the largest atomic radii are located in Group I and are at the bottom of groups.
Which element has the smallest atomic radius phosphorus or tellurium?
Phosphorus (1.23 Å) has an atomic radius smaller than that of tellurium (1.42 Å).
Is smaller than the atomic radius of oxygen?
Yes, the atomic radius of oxygen is larger than the size of an atom. The atomic radius represents the distance from the nucleus to the outermost electron shell of an atom.
Which has the larger atomic radius silicon or bromine?
Silicon has a larger atomic radius than bromine. This is because as you move down a group on the periodic table, atomic radius tends to increase. Bromine is located further to the right on the periodic table and has a smaller atomic radius compared to silicon.
Does Sodium have a larger atomic radius than Aluminum?
No, aluminum has a larger atomic radius than sodium. Aluminum has a greater number of protons in its nucleus compared to sodium, leading to a larger effective nuclear charge that pulls its electrons closer, resulting in a smaller atomic radius.
What is the atomic radius of gallium and how does it compare to other elements in the periodic table?
The atomic radius of gallium is about 135 picometers. In the periodic table, gallium has a larger atomic radius compared to elements to its left and a smaller atomic radius compared to elements to its right.
How does fluorines atomic radius compare to oxygen radius and chlorines radius?
Fluorine has the smallest atomic radius among fluorine, oxygen, and chlorine. Oxygen has a larger atomic radius than fluorine but smaller than chlorine. Chlorine has the largest atomic radius among the three elements.
Which has the largest atomic radius Br or Na?
Na has a larger atomic radius than Br. This is because Na is a metal and atoms in metals have larger atomic radii compared to nonmetals like Br, which has a smaller atomic radius due to its higher effective nuclear charge.
