For each of the following atomic numbers, use the periodic table to write the formula (including the charge) for the simple ion that the element is most likely to form in ionic compounds.
如果atomic number 係35, 咁most likely ion 係咩呀
我真係好唔明白這條chem 點做,

✔ 最佳答案
electron ga 排列係2, 8 ,8, 8 咁ga ma吾係咪用35 - 2 = 33 - 8 = 25 - 8 = 17 - 8 = 9 - 8 = 1
咁最outside就有一粒electron.. 如果佢想stable d 佢就會俾左佢個一粒electron 人地..因為electron 係負ga.. 所以佢俾左一粒人地就會係一粒 1+ ga atom lo..
所以佢係cation

35 is bromine, it belongs to a chemical series of halogens, have charge of 1- in non non gasoeous state, means attract one ion to form an ionic compound, for simple ionic compound, it reacts with 1+, 2+ or 3+ metals, examples are NaBr (sodium bromide), CaBr2 (calcium bromide), AlBr3 (aluminium bromide)...
