S has a larger radius. The atomic radius decreases across a period.
Chlorine (Cl) has a larger ionic radius than sulfur (S) when comparing their anions, specifically the chloride ion (Cl⁻) and the sulfide ion (S²⁻). The ionic radius of Cl⁻ is approximately 181 picometers, while the ionic radius of S²⁻ is about 184 picometers. Additionally, phosphorus (P) in its anionic form (P³⁻) also has a larger ionic radius than sulfur.
Atomic radius increases going down the periodic table and going from right to left, meaning that Fr (Francium) has the largest atomic radius and He (Helium) has the smallest. Therefore, Cl<S<P<Si<Al So the answer is Cl
Bromine (Br) has a larger atomic radius than chlorine (Cl). This is because atomic radius generally increases as you move down a group in the periodic table due to the addition of electron shells. Since bromine is located below chlorine in Group 17 (the halogens), it has more electron shells, resulting in a larger atomic radius.
Calcium has the larger atomic radius than chlorine. Calcium has four energy levels, whereas chlorine has three energy levels. The higher the energy level, the farther it is from the atomic nucleus.
Chlorine has a larger atomic radius than fluorine. This is because chlorine has its outermost electrons in the 3rd energy level, which is farther from the nucleus, and fluorine has its outermost electrons in the 2nd energy level, which is closer to the nucleus.
Cl2 is larger than F2 because chlorine (Cl) has a larger atomic radius than fluorine (F), resulting in larger molecules overall.
The chloride ion (Cl-) is larger than the oxygen ion (O2-). This is because the chloride ion has more electrons than the oxygen ion, resulting in a larger atomic radius and hence a larger ionic radius.
Its Ba, Cl-, for the first 2, not sure on the last one, its confuseing if i had to guess i'd pick Cl-
The S-Cl bond is more polar than the Br-Cl bond. This is because sulfur (S) is more electronegative than bromine (Br), leading to a greater electronegativity difference between sulfur and chlorine (Cl) compared to bromine and chlorine. This larger electronegativity difference results in a more polar bond.
The ionic radius of a typical anion is larger than the radius of the corresponding neutral atom. This is because when an atom gains an electron to become an anion, the extra electron increases the electron-electron repulsion, causing the electron cloud to expand, resulting in a larger ionic radius.

Bromine (Br) is more reactive than chlorine (Cl) and selenium (Se). Bromine has a lower ionization energy and a larger atomic radius compared to chlorine and selenium, making it more willing to participate in chemical reactions.
