The atomic radius of argon is larger than the other elements in the 3rd period because argon is a noble gas with a full outer shell of electrons, leading to increased electron-electron repulsion that causes the electron cloud to expand. In contrast, the other elements in the 3rd period are metals or nonmetals that typically lose or gain electrons to achieve a stable electron configuration, resulting in smaller atomic radii.

Why does sodium have a larger atomic radius than aluminum?
Sodium has a larger atomic radius than aluminum because as you move down a group in the periodic table, the atomic radius increases due to the addition of energy levels. Sodium is located in the third period, while aluminum is in the second period, so sodium has more energy levels and a larger atomic radius.
Which has the larger radius Ca or Kr?
Ca has a larger atomic radius compared to Kr. This is because atomic radius tends to increase as you move down a group on the periodic table, so Ca, being in Group 2, has a larger atomic radius than Kr, which is in Group 18.
Does oxygen have a larger atomic radius than fluorine?
Yes, oxygen has a larger atomic radius than fluorine. Atomic radius decreases as you move across a period in the periodic table from left to right, due to increasing nuclear charge which draws the electrons closer. Oxygen is located to the left of fluorine in the periodic table, so it has a larger atomic radius.
Does phosphorus have a larger radius than chlorine?
No, chlorine has a larger atomic radius than phosphorus. Atomic radius decreases as you move from left to right across a period in the periodic table, and phosphorus is to the left of chlorine in the periodic table.
What has the larger atomic radius sodium or sulfur?
Sodium has a larger atomic radius than sulfur. This is because atomic radius generally decreases as you move from left to right across a period in the periodic table, and sodium is located in the leftmost group while sulfur is farther to the right.
Why does sodium have a larger atomic radius than aluminum?
Sodium has a larger atomic radius than aluminum because as you move down a group in the periodic table, the atomic radius increases due to the addition of energy levels. Sodium is located in the third period, while aluminum is in the second period, so sodium has more energy levels and a larger atomic radius.
Which has a larger radius S or Cl?
S has a larger radius. The atomic radius decreases across a period.
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
Which has the larger radius Ca or Kr?

Does phosphorus have a larger radius than chlorine?
No, chlorine has a larger atomic radius than phosphorus. Atomic radius decreases as you move from left to right across a period in the periodic table, and phosphorus is to the left of chlorine in the periodic table.
What has the larger atomic radius sodium or sulfur?
Sodium has a larger atomic radius than sulfur. This is because atomic radius generally decreases as you move from left to right across a period in the periodic table, and sodium is located in the leftmost group while sulfur is farther to the right.
Which has a larger radius arsenic or phosphorus?
Carbon has a larger atomic radius than nitrogen. The radii of these compounds are 67pm and 56pm, respectively. This occurs because the electrons in nitrogen are more attracted to the nucleus than electrons in carbon.
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.
Why does argon have the smallest atomic radius in period 3?
Argon doesnt have the smallest atomic radius, its chlorine.Argon has the largest atomic radius in period 3.
Why does indium have the largest atomic radius?
Indium has the largest atomic radius among elements in its period because of the shielding effect. With more electron shells, the outer electrons are further from the nucleus, resulting in a larger atomic radius.
How does calcium atomic radius compare to magnesiums radius and potassiums radius?
Calcium has a larger atomic radius than magnesium and a smaller atomic radius than potassium. This trend is due to the increase in number of protons and electrons as you move across the period on the periodic table from magnesium to calcium to potassium.
