It'll have to gain one to have a stable octet.
Bromine has 7 outer electrons, therefore meaning that bromine only needs 1 more to become stable.
Bromine would have to gain one electron in order to obtain a full outer shell of electrons.
Bromine must gain one electron.
it gains electrons.
Bromine will gain one electron.
Bromine and Chlorine both have equal chemical properties. They both have 7 electrons in the outermost energy level. They both gain 1 electron to get the noble gas configuration.Cl and Br have same chemical properties. They have 7 valence electrons. They both are non-metals.
Tetravalent means having 4 valence electrons. The elements in the 14th group are tetravalent. They do not lose or gain electrons. they gain electrons.
Nitrogen has five valence electrons as a neutral atom, but it is shooting for eight. So it needs to gain three more electrons.
Bromine must gain one electron
4
Potassium would lose electrons in all its reactions especially with Bromine.
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.
It must gain two electrons.
Typically just one to acieve the noble gas configuration of krypton. However as bromine is in period 4 its outermost shell is the fourth energy level so it is able to accept more electrons and can form compounds such as BrF5
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.
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.
it gains electrons.
Phosphorus wants to gain three electrons to have 8 valence electrons.
They will gain 3 electrons from something with 3 valence electrons.
