How many electrons must bromine br gain or lose?
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 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?
sodium must lose 1 electron, helium is a noble gas it is in group 8 check your periodic table, sufide ion must gain 2 electrons
What is the number of electrons that Br lost in forming?
Br typically gains one electron to achieve a stable electron configuration, rather than losing electrons.
How many electrons are in Br-80?
The neutral atom has 35 electrons.
How many electrons are in the second shell of ion Br -1?
Eight electrons in the 2nd shell of Br- This is also the number of electrons in the 2nd shell of I-, Cl- and even F- !
How many electrons will bromine gain or lose when forming an ion?
Bromine will gain one electron to become Br-
Which elements do you expect to lose electrons in their chemical reactions Which do you expect to gain electrons Al Sn Br Se?
I would expect the metals potassium, barium, and copper to lose electrons during chemical reactions. I would expect the nonmetals fluorine and sulfur to gain or share electrons depending of the chemical reaction.
Why do halogens gain electrons?
Halogens have 7 valence electrons, in order to become a noble gas you need 8 so instead of losing electrons, it would be easier just to gain 1. That would make Halogens a negative 1 If you do the dot structure you can see that there is only room to gain 1 electron when forming a bond.

Does N and Br gain or lose electron?
Nitrogen atoms gain 3 electrons and form the nitride ion, N3-. Nitrogen atoms also form covalent bonds where they share 3 electrons and do not become ions. Bromine atoms gain 1 electron and form the bromide ion, Br-. Bromine atoms also form covalent bonds when they share 1 electron and do not become ions.
Does bromine lend or borrow how many electrons?
Bromine gain one electron and become Br-.
What is reduced and what is oxidized in Cl2 plus 2NaBr - 2Br plus 2NaCl?
Oxidation is loss of electrons and reduction is gain of electrons. In this case the Cl2 molecule is changed to two Cl- ions by gaining electrons, so the Cl2 is reduced. The Br in the NaBr salt is in the form of Br- ions. The Br- ions are changed to neutral Br atoms (a Br2 molecule) by losing electrons and so are oxidised.
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?
sodium must lose 1 electron, helium is a noble gas it is in group 8 check your periodic table, sufide ion must gain 2 electrons
Which element tends to gain one electron?
Boron, Krypton,Neon, and Radon Krypton, Neon and Radon do not gain electrons. Because an atom wants to have eight electrons in their valence shell or their outermost shell, and Krypto, Neon and Radon are Noble Gases which already have eight in their valence shells, so they don't lose or gain electrons. And as for Boron it want's to gain 5 electrons because it only has three in its valence shell.
What is the number of electrons that Br lost in forming?
Br typically gains one electron to achieve a stable electron configuration, rather than losing electrons.
How many electrons in Br?
To be neutral, Bromine (atomic symbol Br) has 35 electrons. Ions have more or less.
How many electrons are in Br-80?
The neutral atom has 35 electrons.
