Elements on the right of the Periodic Table but not in group 0/8 tend to gain electrons. Those in group 7 tend to gain 1 electron and those in group 6 tend to gain 2.
The metal tends to lose the electron because it has a higher electron affinity, and the nonmetal tends to gain the electron because it has a higher electronegativity. This has to do with the placement of the element on the periodic table. The further to the right you go, the more the element wants to gain electrons in an ionic compound.
Boron, Krypton,Neon, and Radon Krypton, Neon and Radon do not gain electrons. Because an atom wants to have eight electrons in their valence shell or their outermost shell, and Krypto, Neon and Radon are Noble Gases which already have eight in their valence shells, so they don't lose or gain electrons. And as for Boron it want's to gain 5 electrons because it only has three in its valence shell.
No. Atoms can gain and lose electrons but seldom gain or lose protons.

Argon is a Noble Gas. Thus it does not lose or gain electrons.
Fluorine tends to gain electrons
Oxygen tends to gain two electrons to complete its "octet", making it O2- with the electron configuration 1s22s22p6
Oxidation potential is too low. N tends to gain electrons.
The metal tends to lose the electron because it has a higher electron affinity, and the nonmetal tends to gain the electron because it has a higher electronegativity. This has to do with the placement of the element on the periodic table. The further to the right you go, the more the element wants to gain electrons in an ionic compound.
Iodine tends to gain one electron when it forms an ion.
When a bromine atom reacts with a metal, it tends to gain an electron from the metal.
An atom with incomplete octet tends to attain the noble gas configuration by the gain or loss of electrons. If an atom contains 2 electrons in its outer orbit, it would be more energy efficient for it to lose the two electrons and complete the octet, as opposed to gaining 6 electrons for the same.
during a chemical reaction valence electrons are most always transferred
Corrected: All atoms have a neutral charge until they lose or gain electrons. Once they lose/gain electrons then they are considered ions with respectively positive (on loosing) or negative charge (on gaining electrons, as oxygen tends to do).NO: 2-. It's the same as minus 2, but is written as 2- for conventions.
A sulfur atom tends to gain two electrons.
Boron, Krypton,Neon, and Radon Krypton, Neon and Radon do not gain electrons.

Non-metals gain electrons.
