Would the Br ion be bigger than the Se ion?
No. The Se ion will be larger than the Br ion. The more negative the anion's charge, the larger the radius (more electrons = stronger repulsion between the electrons; so, more distance between them). Se would become "Se2-" as an anion, and Br would become "Br1-". Because Se's "2-" anion charge is more negative than Br's "1-" anion charge, and because Se would have more relative electrons to protons than Br, there is more repulsion between electrons, and distance, within the Se ion. So, the Se ion has a larger radius. Hope it helps.
Does selenium have more in common with sulfur or bromine?
Selenium is more in common with Sulfur because they are in the same group. They have the same number of valence electrons and the only elements Selenium is related to is Sulfur and Tellurium. Anna C.

How can you distinguish a metal with non metal with simple physical method?
Nonmetals are gases (Cl, Ar, N...), liquids (Br) or solids brittle and with a very low hardness (S, P, Se..).
Which of the Dobereiner triads shown are still listed in the same column of the modern periodic table?
These triads are: Li-Na-K, Ca-Sr-Ba, Cl-Br-I, S-Se-Te.
What elements has the largest energy out of Sb Pb Se Cl?
cl
When the three elements se te and br ara arranged in order of increasing atomic radius?
Arranging Se, Te, and Br in order of increasing atomic size, you get: Br --> Se --> Te The trends are: atomic size increases right to left, and top to bottom.
What has the greatest electronegativity se s cl?
According to 'Little and Jones' scale Cl 2.83 Se 2.48 S 2.44
