As an example, let's use carbon tetrachloride, CCl4. The single carbon atom contains four valence electrons, and each of the four chlorine atoms contains seven valence electrons. Therefore, the number of valence electrons for this molecule is 4 + (4 × 7) = 32.

For the CH3OCH3 Lewis structure, we have a total of 20 valence electrons. We'll put 2 between the atoms to form chemical bonds, so we've used 16. And we'll put the last 4 on the center Oxygen to complete its octet.

Total valence electrons pairs For, ClO3- there are 26 valence electrons, so total pairs of electrons are 13.

Why are most of the elements on the left and in the middle of the periodic table metals? Because most of them have 3 or less valence electrons. Halogens tend to gain electrons when they react making them nonmetals. ... Halogens tend to gain one electron so that they can get a full outer level and be stable.

In the Lewis structure for PCl3 there are a total of 26 valence electrons. hree pairs will be used in the chemical bonds between the P and Cl.

The halogens all have the general electron configuration ns2np5, giving them seven valence electrons. They are one electron short of having full outer s and p sublevels, which makes them very reactive. They undergo especially vigorous reactions with the reactive alkali metals.

We have 14 valence electrons for Br2. We'll put two between atoms to form a chemical bond.
960866
We have 24 valence electrons for the Cl2CO Lewis structure. We'll put 2 of the electrons between each of the atoms to form chemical bonds.

The halogen elements have seven valence electrons in their outermost electron shell. Therefore, when these elements can receive an electron from another atom, they form very stable compounds since their outermost shell is full.

The number of valence electrons is 7 + 4×7 +1 = 36. If you draw a trial structure in which I is the central atom and every atom has an octet, you will have used 32 electrons. The four extra electrons go onto the central I atom as two lone pairs.

there are 15 electrons in total, there must be 5 electrons at the third energy level. there are 3 energy levels, so the electrons at the third are outer, or valence, electrons. this means that there are 5 valence electrons. all neutral atoms of the elements in group 5 have 5 valence electrons.

Answer and Explanation: In the CH3 Cl molecule, the total number of valence electrons is 4 × 1 atom (C) + 1 × 3 atoms (H) + 7 × 1 atom (Cl) = 14.

['So group seven, aka the halogens. ... ', 'From the lowest boiling and melting point to the highest, the group in order is fluorine, chlorine, bromine, iodine and astatine.', 'As you move down the group the halogens become darker in colour. ... ', 'Each element has five electrons in the outer p shell.']
