Xenon never gains or loses electrons, because it is in the vertical group of Noble Gases, located at the far right side of the Periodic Table. These gases include helium, neon, argon, krypton, xenon, and radon. They do not want to gain or lose electrons because they already have their orbital shells filled with the maximum number of electrons.
Here are a few examples:
The first orbital shell (which is the space that electrons can circle the nucleus in) can hold two electrons.
Helium has two electrons, so it is happy with the number it has. The second orbital shell can hold eight electrons.
Neon has 10 electrons, two in the first shell, and eight in the second shell. So it is happy with the number of electrons it has because it's orbital shell is full.
Fluorine has only nine electrons, and it seeks another electron because it does not want to hold it's second orbital shell if it cannot be full.
Neither. It has a stable octet in its ground state.
it is a noble gas, it doesn't do either one
Covalent bonds do not gain or lose electrons, but rather share electrons.
Polonium lose electrons.
sn lose 4 electrons

Share.
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.
