it gains electrons.
gains
It'll have to gain one to have a stable octet.
Bromine will gain one electron.
In phosphene it gain 4 electrons. Phosphate lose 4 electrons
It loses electrons.
Polonium will neither gain nor lose electron. it will prefer to form covalent compounds by sharing of electrons.
Potassium would lose electrons in all its reactions especially with Bromine.
Bromine must gain one electron
Bromine will gain one electron to become Br-
4
It'll have to gain one to have a stable octet.
None - it would have to GAIN one.
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.
Bromine will gain one electron.
Bromine, like Fluorine and Chlorine, is an Halogen. Halogens gain an electron to become X^(-) anion. 'X' being the general symbol for an halogen.
No. Atoms can gain and lose electrons but seldom gain or lose protons.
Covalent bonds do not gain or lose electrons, but rather share electrons.
It needs to gain 3 electrons than to lose 5 electrons. So phosphorus has to gain 3 electrons.
