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.
Bromine must gain one electron
Bromine must gain one electron.
Bromine would have to gain one electron in order to obtain a full outer shell of electrons.
Potassium would lose electrons in all its reactions especially with Bromine.
Atoms with eight valence electrons usually do not gain or lose electrons. Atoms with one, two, or three valence electrons will lose electrons.
It must gain two electrons.
As a general rule, the noble gases do not lose or gain valence electrons because in most reactions they are considered inert.
P has 5 valence electrons so it can gain 3 electrons or lose 5 electrons to have a full valence shell.
Phosphorus wants to gain three electrons to have 8 valence electrons.
Bromine will gain one electron to become Br-
Beryllium can lose its two valence electrons.
It is going to lose electrons
Bromine tends to gain 1 electron. It can however gain them when bonding with Chlorine, oxygen and fluorine.
This is a metal so it will lose its valence electrons.
atoms lose, gain, or share valence electrons to have 8 valence electrons.
It will lose 2 electrons.
This atom gain two electrons.
Sulfur must gain two electrons.
Compounds will gain or lose electrons in order to reach a more stable state, ideally a full valence shell.
It loses 2 electrons to obtain the argon configuration of 8 valence electrons.
The valence shell can hold 8 valence electrons Each element is striving to achieve stability which is acquired by either: having 8 valence electrons or losing all of the valence electrons. for example carbon has four v. electrons so it can either gain or lose 4 in order to maintain stability. You many gain or lose electrons by bonding.
Oxygen is an oxidizer, it will gain electrons in a reaction to complete it's valence shell.
Either lose 5 electrons, which is least likely, or gain 3 electrons.
