Boron can lose 3 electrons from its valence shell that is 2 in 2s & 1 in 2p sub-shell, wheras it cannot gain electron b'coz of its electropositive nature & it has less electron affinity.

How many valence electrons must bromine gain or lose to get 8 valence electrons?
Bromine's atomic number is 35, so it has 7 valence electrons. To achieve 8 valence electrons and a full outer shell, bromine needs to gain one electron.
How many electrons does Si gain or lose?
Silicon (Si) can gain or lose 4 electrons. It can either gain 4 electrons to have a stable octet configuration or lose 4 electrons to achieve a stable configuration.
How many electrons must be gained or lost for each of the following to achieve a noble gas electron configuration Lithium atom Bromine atom Barium ion Helium atom?
Lithium atom: Gain 1 electron Bromine atom: Lose 1 electron Barium ion: Lose 2 electrons Helium atom: No electrons need to be gained or lost

How many valence electrons must bromine gain or lose to get 8 valence electrons?
Bromine's atomic number is 35, so it has 7 valence electrons. To achieve 8 valence electrons and a full outer shell, bromine needs to gain one electron.
How many electrons will Bromine have to lose to have the same electron configuration as Krypton?
Bromine (Br) has 35 electrons, while Krypton (Kr) has 36 electrons. To have the same electron configuration as Krypton, Bromine would need to lose one electron.
Will Se lose or gain electrons and how many?
Se will gain electrons
How many electrons will bromine gain or lose when forming an ion?
Bromine typically gains one electron when forming an ion to achieve a stable electron configuration. The electron configuration for a bromine ion is [Kr] 4d10 5s2 5p6, which is the same as that of a noble gas.
How many electrons does Si gain or lose?
Silicon (Si) can gain or lose 4 electrons. It can either gain 4 electrons to have a stable octet configuration or lose 4 electrons to achieve a stable configuration.

How Many electrons will iron gain or lose when it forms a ferric ion?
it will lose 3 electrons
How many electrons will selenium lose or gain in forming an ion?
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
How many valence electrons does bromine has to lose or gain to have 8 valence electrons?
Neutral Bromine has three complete rings of electrons. The first ring consists of 2 electrons, the second has 8, the third 18, and the fourth has a maximum capacity of 8 electrons. Bromine only has 7 electrons in it's outer ring, though, so it needs one extra electron to complete it's ring. So to answer your question, it needs ONE more valence electron.
When forming an ion bromine is most likely to gain how many electrons?
Bromine is most likely to gain one electron when forming an ion, as it is in Group 17 of the periodic table (halogens) with 7 valence electrons. By gaining one electron, bromine achieves a stable octet and forms a Br- ion.
How many electrons do the Lanthanides lose or gain?
