ionic bonding :]
atoms either loose or gain a maximum of 2 valence electrons like hydrogen
They will loose electrons.
To form a molecule, atoms can share, lose, and gain electrons
When atoms gain, lose, or share electrons, they form chemical bonds, leading to the creation of ions or molecules. Gaining or losing electrons results in the formation of ions: atoms that are positively charged (cations) when they lose electrons, or negatively charged (anions) when they gain electrons. Sharing electrons typically occurs in covalent bonds, where two or more atoms form a stable molecule by overlapping their electron clouds. These interactions are fundamental to the formation of compounds and the chemical behavior of substances.
Most atoms have the ability to lose electrons, given the conditions are favorable, e.g. in a chemical reaction, but the ones that loose their electrons easiest are the ones with only a few electrons in their outer shell, such as the alkali metals and alkaline earth metals which only have 1 and two electrons, respectively.
other atoms, some loose protons, electrons, and neutrons (which get attached to other atoms and change them) and energy.
They need to gain them.
they add or loose electrons from the outer most shells
conduction band electrons detach themselves from atoms and become delocalized
None the formation of an ion has nothing to do with losing or winning atoms.
An atom with 3 electrons in level M would tend to either gain 5 electrons to complete level M or lose 3 electrons to complete the previous level. The tendency would depend on the element and its electronegativity.
