How many electrons are in the third shell of bromine?
The 3rd shell holds 8 or 18 electrons.
How many electrons can the 4 shell hold?
32
This model breaks down at the n=3 shell because each shell has subshells. There are 4 subshells, s, p, d, and f. Each subshell can hold a different number of electrons….Search form.
| n= | Shell | Maximum Number of Electrons |
|---|---|---|
| 2 | 2nd Shell | 8 |
| 3 | 3rd Shell | 18 |
| 4 | 4th Shell | 32 |
Why does BR have 7 valence electrons?
Bromine has an electron configuration of 1s22s22p63s23p64s23d104p5 the valence electrons are in the 4s and 4p orbitals giving Bromine 7 valence electrons.
How many electrons are in the highest occupied level of bromine?
Bromine is a member of the halogen family of elements. Its companions include fluorine, chlorine, and iodine. Like the other halogens, bromine has seven electrons in its outer shell and is very reactive.
Is it 8 or 18 electrons in third shell?
So the third shell can be considered to hold 8 or 18 electrons but in total the third shell can hold 18 electrons.
What is the 2 8 8 rule in chemistry?
There is a 2-8-8 rule for these elements. The first shell is filled with 2 electrons, the second is filled with 8 electrons, and the third is filled with 8. You can see that sodium (Na) and magnesium (Mg) have a couple of extra electrons. They, like all atoms, want to be happy.
Why are there 18 electrons in the third shell?
Each shell can contain only a fixed number of electrons, up to two electrons can hold the first shell, up to eight (2 + 6) electrons can hold the second shell, up to 18 (2 + 6 + 10) can hold the third shell and so on. The general formula is that the nth shell can hold up to 2(n2) electrons in principle.
How many electrons are in the highest energy level of bromine?
Its companions include fluorine, chlorine, and iodine. Like the other halogens, bromine has seven electrons in its outer shell and is very reactive. You will find bromine in many salt compounds with alkali metals.
How many neutrons are there in a bromine atom?
There are about 45 neutrons in Bromine. Bromine is a nonmetal. Since Bromine is in group, or series, 17, it has 7 valence electrons. Group 1 on the periodic table has 1 valence electron. Group 2 on the periodic table has 2 valence electrons.
How many electrons does bromine have in series 17?
Therefore, if Bromine is in series 17, 17-10 is 7, so Bromine has 7 valence electrons. The electron dot diagram to the left depicts the number of valence electrons bromine has. The dots are arranged in a specific pattern to show how many valence electrons Bromine has.
Where can bromine be found in the body?
Its companions include fluorine, chlorine, and iodine. Like the other halogens, bromine has seven electrons in its outer shell and is very reactive. You will find bromine in many salt compounds with alkali metals. Sodium bromide is a compound found in seawater.
How are the valence electrons arranged in bromine?
The electron dot diagram to the left depicts the number of valence electrons bromine has. The dots are arranged in a specific pattern to show how many valence electrons Bromine has. To the right is a diagram explaining the placement of the valence electrons in an electron dot diagram.
