Sodium and chlorine don’t actually overlap or anything, Single bonds are different to covalent bonds. Does it make sense that a chlorine atom would accept two electrons? TWO ELECTRONS IN 1st SHELL AND 3 ELECTRONS IN OUTERMOST SHELL.SO TO GET CONFIGURATION IT HAS TO FORM TRIPLE BOND.SO IT NEEDS STILL 3 ELECTRONS TO GET STABLE. Although he suggested the bond was (actually “might be“) covalent, this seemed less something that he confidently recalled, than something he was inferring from what he could remember – or perhaps even guessing at what seemed reasonable: “they might be just, they might be like, be covalently bonded“. Borane is the name scientists have when one boron (B) atom bonds to three hydrogen (H) atoms. The number of neutrons is calculated by subtracting the atomic number from the mass number. They might be just, they might be like, be covalently bonded. What is its valency and why? Notify me of follow-up comments by email.

Beside above, what is the number of protons and electrons in chlorine? Weegy: Carbon has four electrons in its outer shell. The boron atom has lost its three extra electrons, giving it a full shell as well. How many unpaired electrons does chlorine have? Given his apparently confused notion about the C-Cl bond I decided to turn the conversation to a covalent bond which I knew, well certainly believed, was more familiar to him. Now Umar had recalled that chlorine comprises of covalent molecules, I asked him about the nature of the bond: So what would that be, covalently bonded? Chlorine has 7 electrons in its valence shell, making it highly electronegative. Perhaps the earlier context of talking about polar bonds and the trichloroethane molecule somehow acted as a kind of impediment to Umar remembering about the chlorine molecule. So how many electrons would they have then? You can see that each of the hydrogen atoms now has two electrons, filling their outer shell. d.
