WebElectronegativity is the tendency of an atom to attract a bonding pair of electrons. Explain the trend in oxidising ability of the halogens! The halogens become less oxidising down the group because: 1. The atoms get larger. 2. The outer shell is further from the nucleus, so electrons are less strongly attracted to it. WebQ. THE HALOGENS Q3 All the halogens form binary hydrogen com‑ pounds with the general formula HX(g), where X is one of the halogens. Hydrogen fluoride, HF(g), is a highly irritating, corrosive, colorless gas. It can be prepared by the reaction described by the equation CaF 2 (s) + H 2 SO 4 (aq) → CaSO 4 (s) + 2 HF(g) simple chicken fry recipe
