How many electrons are present in the valence shell of the central atom in each of the following species? (a) $\mathrm{SCl}_{2} ;$ (b) $\mathrm{H}_{2} \mathrm{O} ;$ (c) $\mathrm{NH}_{3} ;$ (d) $\left[\mathrm{NH}_{4}\right]^{+} ;(\mathrm{e}) \mathrm{CCl}_{4} ;(\mathrm{f})$ $\mathrm{PF}_{3} ;(\mathrm{g}) \mathrm{BF}_{3} ;(\mathrm{h}) \mathrm{BeCl}_{2} .$ Comment on the answers obtained.

You two have been going on for since before, which, as you look at the real intellect Trump's of to a friend you're under Frankel elements. So I was seen on Has he'd be until, like, drunk, because it is a noble gas going into the current drunk him to. Plus it has drunk humor. He has to We're willing to electrons. But since you use them, you would have Meet me in into account in your own show. You would similes krypton. Chlorine would have someone really two electrons and chlorine ion would have meat, rain intellectuals.

Local bond is known to be lasting interaction between atoms, ions or molecules which enables the formation of chemical compounds Here, we're looking to determine the number of valence electrons. So we can define valence electrons as the number of electrons in the most outer shell. So we'd like to determine surveillance electrons for n H two for c l 02 minus for h C N and for s n c L four. So with the fast example, nitrogen is group five 25 electrons add one, multiplied by two for the hydrogen and then add one for the negative charge. We get eight valence electrons and cielo to minus what we have is seven from the chlorine at two times six for the oxygen at one for the negative charge, we get 20 valence electrons in total. Next we have H C N. So we've got one electron from the hydrogen, add four electrons from the carbon carbons group four at five electrons from the nitrogen because nitrogen is group five. So what we have is 10 valence electrons. The final example, we've got 10, so we have four electrons for that, and then we need to add for lots of of seven for the chlorine is, and this gives us 32 valence electrons available.

So we're asked to count the number of valence electrons in each of the following ions or molecules for par. A nitrogen has five valence electrons. Each of the two hydrogen has one, so two times one And then we'll add one because This negative sign means that one electron was gained. So this is six plus two or eight for part B chlorine is seven, therefore oxygen's each of them is six and again plus one because of the negative charge. So this is eight plus 24. This is 32 In total valence electrons. For part C, hydrogen is one carbon is four and nitrogen is five, So that's a total of 10 and for part D um 10 is four oops And each of the four chlorine is seven. For a total of 32.

Okay, so what? This question? They're asking how maney balance electrons that speech of the Adams half. So what is a balance electron? So I Valence Electron is pretty much the number of electrons that populate the outermost show of an atomic order put up for bid. Oh, for example, let's say we have Adam a right. It's first show always, no matter what. Adam, it's versatile, always fits two electrons. Now its second shell fits eight. So let's say this show only has seven electrons 4567 right. It can fit eight electrons, but this there's only seven electrons, and we see that there is no more show outside because there's no more electrons to fill out more of the outer shell. This means that this shell is the Valence electron shell, and the number of electrons in this show is the Valence Electron. So we see that we have 1234567 districts that this element A has seven valence electrons. So that is what a down Solectron is. And we can easily figure out at an elements balance electron just by looking at the group number that the element belongs to So that's what we're gonna do. So we have sodium. So all you need is a period of tape periodic table. To figure this out, we have sodium. We see that sodium is element number 11. And when we look at the periodic table, we see that element Number 11 belongs to Group one A. So group is going down DPR table and period is going from left to right. So we see that it's in Group One A. So it's a group one Age means that it has one balance the lifetime. And now we see Bebe is C l. So chlorine. Well, we should. Chlorine isn't group seven A. So we have seven bounce electrons. Now we go to see for see, we have element. I fell silk. Um, we feel so comb belongs to group for a So silicone has four valence electrons nef for D We have element B, which is boron. So boron is element number five and it belongs in three a of the periodic table. So has three valence electrons. Now we go to e we have neon, so neon is element number 10 And if we go to the fair table we see that over Number 10 belongs to group Ate A so has eight valence electrons. And now, for the last part, we have Matt Region. So when we go to Paris table we see the nitrogen is element number seven and seven belongs to group five A just means that has five Valence electron and those are all of our answers.
