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. WebEffect of pH on halogen composition in emissions from selected seaweeds. Among the seaweeds, K. alvarezii, the only commercially cultivated species observed, emitted the largest amount of halogens at all pH levels except for 7.8 (ambient) (Table 3). This was also observed in T. conoides, the second largest emitter of all the seaweeds.
