Drawing the Lewis Structure for CBr4 (Carbon Tetachloride)
The elements that belong to the same group in the periodic table possess same number of valence electrons. Fluorine, chlorine, bromine and iodine, all belong to the same group, Group 17 of the periodic table. So, all these elements possess same number of valence electrons. The Ionic bond formed between Potassium and Bromine is created through the transfer of electrons from Potassium (metal) to Bromine (nonmetal). Potassium is located in group 1 which means that potassium has one valence electron; Bromine is located in group 17 which means that it has seven valence electrons.
Viewing Notes:
- The Lewis structure for CBr4 is similar to CCl4. Since they are in the same Group on the periodic table they each have the same number of electrons (7) their structures are similar.
- The Carbon atom goes in the center of the Lewis structure since it is the least electronegative.
- For the CBr4 Lewis structure there are a total of 32 valence electrons available.

Transcript: This is the CBr4 Lewis structure: Carbon Tetrabromide. Carbon is in group 4 or 14, so it has 4 valence electrons. Bromine in group 7 or 17, so it has 7, and we have 4 Bromines. So 4 plus 28 equals 32 total valence electrons. Carbon, that's the least electronegative, that'll go in the center; and on the outside we'll put the Bromine atoms. We'll put 2 electrons between atoms to form chemical bonds, and we've used 8.
And then we'll go around the outside and fill the octets for the Bromine until we've used 32 valence electrons. So we have 8, 10, 12, and 32. So we've used all 32 valence electrons. Each of the Bromines has 8 valence electrons, and the central Carbon has 8 valence electrons as well.

Similarly, what happens when a bromine ion becomes an ion?
IONS Bromine Can MakeTo become an ion, an element has to gain or loose electrons. If it gains electrons, it receives a negative charge because it then has more electrons than protons. This is known as an anion. If it looses electrons, it receives a positive charge because it has more protons than electrons.
Furthermore, does bromine gain or lose electrons? Bromine atoms tend to gain just one electron to get to a full octet, as Bromine is in Group VII. A chemical consisting of an aluminum ion and a bromide ion in their stable states would be AlBr2+, but it is not an ionic compound because it has a charge. Thus it tends to lose two electrons.
Also question is, will a bromine atom form a positive or negative ion Why?
Total Valence Electrons Bromine
The neutral atom of bromine has 35 electrons because the number of electrons equals the number of protons. c) Bromine gains an electron, what is the resulting ion called and is it positively or negatively charged? When bromine gains an electron, the resulting ion is called an anion and is negatively charged.
Bromine Has 17 Valence Electrons
What type of ion does bromine form?
Bromine Number Of Valence Electrons
A bromide is a chemical compound containing a bromide ion or ligand. This is a bromine atom with an ionic charge of −1 (Br−); for example, in caesium bromide, caesium cations (Cs+) are electrically attracted to bromide anions (Br−) to form the electrically neutral ionic compound CsBr.
