WebEach Cl atom interacts with eight valence electrons: the six in the lone pairs and the two in the single bond. The Octet Rule The other halogen molecules (F 2, Br 2, I 2, and At 2) form bonds like those in the chlorine molecule: one single bond between atoms and three lone pairs of electrons per atom.
Web9 Apr 2024 · rrange the atoms and/or ions in the following groups in order of decreasing size. msp;a.O,O,O2b.Fe2+,Ni2+,Zn2+c.Ca+,K+,Cl. Define valence shell and valence electron. For each of the following atoms or ions, state the total number of electrons, the number of valence electrons, and the number of core electrons. (a) Rn (b) Sr+ (c) Se2 (d) Sb2. WebThe octet rule reflects the observation that the most stable ions of many elements have eight electrons in their valence shell for gaining the best possible stability. Chlorine, for example, typically forms an anion with a charge of -1 −1, while sodium typically forms a cation with a charge of +1 +1.
WebThe Octet Rule and Its Exceptions. The octet rule states that atoms below atomic number 20 tend to combine so that they each have eight electrons in their valence shells, which gives them the same electronic configuration as a noble gas. The rule is applicable to the main- group elements, especially carbon, nitrogen, oxygen, and the halogens ...
