How many valence electrons does a bromine anion contain?
A bromine anion has 8 valence electrons. This is because bromine, with 7 valence electrons, gains one extra electron when it forms an anion to achieve a full octet and become stable.
How many valence electrons dose a bromine anion contain?
A bromine anion (Br-) contains 8 valence electrons. Bromine is in group 7A of the periodic table and has 7 valence electrons. When it gains an extra electron to form an anion, it now has a total of 8 valence electrons.
Number of valence electrons in xenon?
Xenon has 8 valence electrons.
What is the highest number of valence electrons an atom can have?
The most valence electrons an atom can contain is eight.
How many valance electron does krypton have?
Since krypton is a noble gas in the group number 18, it has 8 valence electrons. Eight is the maximum number of valence electrons.
Bromine atoms always gain one electron when they become an ion which atom has the same number of electrons as a bromine ion?
An iodine atom has the same number of electrons as a bromine ion. Both elements belong to the halogen group and have seven valence electrons. When bromine gains one electron to become an ion, it will have a full outer shell with eight electrons, the same electron configuration as iodine.
Which group contains the least number of valence electrons?
Noble gases contain the least number of valence electrons, with a full outer shell of eight electrons (except for helium, which has two valence electrons).
How many valence electrons are found in a krypton atom?
A krypton atom has 8 valence electrons in the 4s and 4p orbitals.
What is the maximum number of electrons that might be found in the valence shell?
The maximum number of electrons that can be found in the valence shell is 8. This is known as the octet rule, which states that atoms tend to gain, lose, or share electrons to achieve a full valence shell of 8 electrons.
How many valance electrons does bromine need to have a full valance shell?
it only needs 1 more valence electron. it has seven and wants eight like all ofthe other elements.
Does krypton have 8 valence electrons?
Yes, krypton has eight valence electrons.
How valence electrons does helium have?
Helium has two valence electrons. It is the only noble gas not to have eight valence electrons. Helium has the electronic configuration 1s2.The Noble gases have eight valence electrons in their outer shell.
