How many additional valence electron shells does bromine need to have a full valence shell?
It needs only 1 more electron since it already has 7 valence electrons.

How many core and valence electrons are in bromine?
Bromine (Br) has 35 electrons in total. It has 7 valence electrons (outermost shell) and 28 core electrons (inner electron shells).
Why does bromine have higher ionization energy then lead?
Bromine has less valence shells than lead making the distance between its valence electron and its nucleus less than that of lead. This means that there is greater attraction between the nucleus and electron for bromine and it requires a higher ionisation energy to remove its electron.
How many electrons are in the valence shell of francium?
Francium has one valence electron, its atomic no is 87 and it belong to Ist group of periodic table.
Group 1a elements have how many electrons in their valence shells?
All these have one electron in their valence shell.
As you move across a period elements have the same number of?
As you move across a period, elements have the same number of electron shells but different numbers of valence electrons. This leads to differences in reactivity and chemical properties across the period.
How many electron shells does bromine have?
Bromine has 4 electron shells.
How many core and valence electrons are in bromine?
Bromine (Br) has 35 electrons in total. It has 7 valence electrons (outermost shell) and 28 core electrons (inner electron shells).
How many valence shells in radium?
Radium has seven electron shells; the valence of radium is 2+.
How many core electrons are in bromine?
2,8,18,7... 28 core electrons 7 valence electrons.
Why does bromine have higher ionization energy then lead?
Bromine has less valence shells than lead making the distance between its valence electron and its nucleus less than that of lead. This means that there is greater attraction between the nucleus and electron for bromine and it requires a higher ionisation energy to remove its electron.
What is the total of valence electrons of BrO31?
Every oxygen atom has -2 as its oxidation number (and 8 electrons in its valence shells). By balancing the charges, bromine is in +5 state: +6 with six bonds with oxygen and -1 from central charge. After counting the electron that is not involved above--bromine has 14 electrons in its valence shell.
How many electrons are in the valence shell of francium?
Francium has one valence electron, its atomic no is 87 and it belong to Ist group of periodic table.
How many valence shells does the element neon have?
Period number = no. of electron shells. Therefore neon has two shells.
Group 1a elements have how many electrons in their valence shells?
All these have one electron in their valence shell.
Why is iodine larger than bromine?
Iodine's electron configuration is 2, 8, 18, 18, 7; bromine's is 2, 8, 18, 7. At the simplest level of modelling there is one more electron shell occupying space in an iodine atom than in one of bromine.
What are stable electron configurations are likely to contain?
completely filled valence shells
How many electron shells in 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. You will find bromine in many salt compounds with alkali metals. Sodium bromide is a compound found in seawater. As with all reactive elements, bromine is never found alone in nature. It is always a part of a compound with other elements. Source: Chem4kids
