It can do both. It gains electrons in Phosphene, loses electrons in Phosphate.
In phosphene it gain 4 electrons. Phosphate lose 4 electrons
If phosphorus forms a monatomic ion, it gains electrons and form a phosphide ion. More commonly, however, phosphorus forms a polyatomic anion including one or more oxygen atoms. The bonds within these polyatomic anions are covalent, but phosphorus is considered to have a positive oxidation number in such anions, and positive oxidation number corresponds to losing electrons.
It loses electrons.
it gains electrons.
Polonium will neither gain nor lose electron. it will prefer to form covalent compounds by sharing of electrons.
Phosphorus wants to gain three electrons to have 8 valence electrons.
It needs to gain 3 electrons than to lose 5 electrons. So phosphorus has to gain 3 electrons.
In phosphene it gain 4 electrons. Phosphate lose 4 electrons
Phosphorus wants to gain three electrons to have 8 valence electrons.
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.
Lose
When atoms lose or gain electrons, they form ions. These are charged particles.
Se will gain electrons
Lose electrons is oxidation. To gain electrons is reduction.
If you mean Metals... No, they do not gain electrons, they actually lose electrons because it is a lot easy for them to lose them so they can gain stability much faster.
