SiBr4EDIT: While the above answer is correct, that is actually the molecular formula, which is not what the question is asking. In order to determine a molecule's lewis dot structure, follow these steps:1. Count the number of valence electrons (e-) for each atom.Bromine 7 valence e- X 4 atoms = 28 e-Silicone 4 valence e- X 1 atom = 4 e-Total valence e-: 32 e-2. Determine which atom is the central atom; draw "skeleton" of structure. Typically the central atom is either a. the only atom that occurs once in the molecule and/or b. is the atom that can form the most bonds (least number of valence e-). In this case, silicone is the only atom that occurs twice and can form the most bonds (4 bonds, as it has 4 valence e-). Join all atoms using only single bonds (single lines).3. Add lone pairs (dots) to each atom accordingly. This is determined by subtracting the number of lines (step 2) from the total of valence e- (step 1). Each line represents a pair of electrons (2 e-). Note: if the total obtained in step 1 is the same as the number achieved in this step, you are done (notapplicable in this case). Place the dots around surrounding atoms first, then place any leftover dots on central atom (ifapplicable).32 - 8 (4 bonds are created [4 bonds x 2 e- each = 8]) = 24 e- (24 dots to be drawn).In this case, there will be 6 dots around each bromine atom, as 1 pair is shared with the central atom (silicone).4. Make sure the octet rule (duet rule for hydrogen always) is represented for all elements involved in bond(s). If an atom does not have 8 e- attached (for atoms where the duet rule applies [ex. hydrogen, represented by a single line]), double or even triple bonds may be necessary to achieve the octet rule for all atoms.In this case, all atoms have achieved the octet rule with single bonds.According to the VSEPR model, since this molecule has 4 atoms bonded to the central and has 0 unshared e- pairs on the central atom, the molecule's geometric shape is tetrahedral, meaning the bond angles are formed at about 109.5 degrees Celsius.
For this dot structure, start with the Be atom in the center. On the left and right sides are a single bond attached to a Cl atom. The unbonded sides of the Cl atoms then each have a pair of dots.
This shows the BONDING PAIRS, the dots are from the oxygen and the commas show the chlorine electrons. the oxygen will have 2 lone pairs and the chlorine atoms both ave 3 lone pairs each. hope this helped
E. All of the above choices are correct.
Two molecules of Carbon monoxide. I think not two molecules but two moles of carbon monoxide .i,e 2CO.
The name "Zoë" with two dots above the "e" is pronounced as "Zoh-ee" with a long "o" sound and emphasis on the second syllable.
My name is bronte so i know. firstly.....two dots on top of the 'e' next to each other not on top of each other. and you pronounce it- 'bron-ti' though DO NOT emphisize the 'i' but 'bron-tee' however you wish to say it :)
All you have to do is hold in the e key and go up or down with you blackberry's trackpad or scrollerball.
It depends on where you live but here is how you say mother: *nene or mama The e's have two dots above them.
I think they are supposed to e-bombs, since you usually need two these days.
Me* pelqen. or Te* kam enqef. At least that's how i would say it *e with two dots above it.
Go to start -> Programs -> Accessories -> Accessibility -> Character Map then find it in there. Then it's a matter of copy and pastё.
I think the two dots are an umlaut. In that cas it is pronunced as if there were an e after the a. 'Staer'
Press the option key and then press u Then type e
Those dots are called an "Umlaut". They indicate that the e should be pronounced separately. So it's not pronounced Noel, like the name Joel. It's pronounced as No-El.
Geseen enn. (Two dots on top of the e after the s in Gesseen.)
