Metallic chromium atoms tend to lose electrons in a chemical reaction. The chromium in a compound may either gain or lose, depending on the reaction.
Iron (Fe) can both give or receive electrons, depending on what it is reacting to. Fe exists in a wide variety of oxidation states, though 2+ and 3+ happen to be the most common.
Chlorine gains and shares electrons
It loses electrons.
Technetium lose electrons being a metal.
In phosphene it gain 4 electrons. Phosphate lose 4 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.
It can do both. It gains electrons in Phosphene, loses electrons in Phosphate.
No. Atoms can gain and lose electrons but seldom gain or lose protons.
It needs to gain 3 electrons than to lose 5 electrons. So phosphorus has to gain 3 electrons.
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
In phosphene it gain 4 electrons. Phosphate lose 4 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.
Polonium lose electrons.
sn lose 4 electrons
Sodium lose electrons becoming a cation.
