As a general rule, the noble gases do not lose or gain valence electrons because in most reactions they are considered inert.
Elements want to gain or lose electrons in order to achieve a stable electron configuration, usually by attaining a full valence shell of electrons. This helps them achieve a more stable, lower energy state, similar to the configuration of noble gases.
Groups determine the number of electrons on the outer shell of an atom. When elements react, they want to complete their outer most shell. Filling the outer most shell is called the octet rule. In the cases of groups 1, 2 and 3, they want to donate, 1, 2 or 3 electrons to lose the outer most shell and form a completed outer shell.
Oh, dude, elements that gain 2 electrons when they combine with another element are found in Group 16 of the periodic table, also known as the oxygen group. This includes elements like oxygen, sulfur, and selenium. So, like, when these elements bond with others, they're all like, "I'll take two electrons, thanks!"
Because they are all trying to be like noble gases. Noble gases are like the templates that all other elements what to be like because they are stable. They lose different numbers because they all have different amounts of electrons to begin, so it would make since that they would have to lose different amounts of electrons to get to 8 (the amount of electrons a noble gas has). Hope that helps
These elements are called ions. Elements choose to lose or gain electrons because they want to achieve electronic stability. All metals lose electrons and all non-metals gain electrons to get the respective stable electronic structure they want. As for metalloids, some elements in there gain while some lose electrons. When elements lose or gain electrons, they will form a charge, since the number of protons and neutrons are not balanced now. All non-metals form negative charged ions while all metals form positive charged ions. Compounds are formed when a positively charged ion is attracted to an negatively charged ion by the electrostatic force of attraction. For example, sodium chloride is a compound of sodium ion and chlorine ion. The positively charged sodium ion is attracted to the negatively charged chloride ion to form the compount.
As fluorine is a halogen (the group in which the elements are more reactive as they are one electron lesser than that of the octet configuration)and hence it can only gain electrons.
they will lose electron to form mono positive cation

Lose 2Alkaline-earth metals have 2 outer shell electrons. All atoms "want" eight. They will achieve a full outer shell by losing or gaining the least number of electrons. Since group 2A elements have two valence electrons, they would either have to gain 6 electrons or lose 2. It is easier to lose 2.
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.
Magnesium has two valence electrons in its outer shell and typically loses these electrons to achieve a stable electron configuration, similar to that of noble gases. By losing two electrons, Magnesium becomes a positively charged ion (Mg²⁺). Therefore, Magnesium wants to lose 2 electrons rather than gain any.

Argon is a Noble Gas. Thus it does not lose or gain electrons.

They can do either - and they will. This is the fundamental mechanism behind the science we know as chemistry. Or Yes, they do. Some want to borrow some and some want to loan some out. This is the fundamental mechanism behind the science we know as chemistry.
