What elements have the highest electronegativity between (as) (se) (br) and (ge)?

Among the elements arsenic (As), selenium (Se), bromine (Br), and germanium (Ge), bromine (Br) has the highest electronegativity. Electronegativity generally increases across a period and decreases down a group in the Periodic Table. Bromine, being in Group 17 (halogens), is more electronegative than the other elements listed. Selenium (Se) is next, followed by arsenic (As) and germanium (Ge).
