The non metals. (this ignores the special case of transition metals see the linked answer for info. on this topic.)
They are called valence electrons. Ionic is a bond between a nonmetal and a metal. A covalent bond(molecular bond) is between two or more non metals.
gain electrons to achieve a stable electron configuration. This transfer of electrons allows the nonmetal to achieve a full outer electron shell, making it more stable and creating an ionic bond between the atoms.
Nonmetals will undergo chemical reactions that result in a stable electron configuration of 8 electrons in the outer shell. The number of valence electrons tells you have many they have in their outer shell prior to any chemical reaction, and therefore, how many more electrons they need to get a complete set of 8. So for example, oxygen has 6 valence electrons and therefore needs 2 more to have 8, so it will form an ion with a charge of minus two, which is the charge that is carried by the additional two electrons that oxygen will acquire. Chlorine has 7 valence electrons, therefore it needs just one more electron to complete its outer shell, and as an ion will have a charge of minus one. Nitrogen has 5 valence electrons, so it needs 3 more, and will form an ion with a charge of minus three.
Yes, the reactivity of a metal does depend on how easily it loses its valence electrons. Metals that lose electrons easily are more reactive because they can form positive ions more readily. This is why alkali metals, which have only one valence electron, are highly reactive.
This atom become an anion with negative charge -1.
The outer electrons of a metal atom that bonds with a nonmetal atom are either transferred to the nonmetal to form an ionic bond or shared with the nonmetal to form one or more covalent bonds.

No. If the reaction described occurs at all, it would form a covalent coordinate bond.
Selenium is a nonmetal, as it is located in Group 16 of the periodic table and typically forms covalent bonds. Rubidium, on the other hand, is a metal, specifically an alkali metal found in Group 1. The significant difference in their valence electrons reflects their distinct chemical properties, with selenium being more electronegative and reactive with nonmetals, while rubidium readily loses its single valence electron in reactions.

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.
Yes. Metals have lower electronegativities than nonmetals, and they tend to have fewer than four valence electrons, so they are more likely to lose electrons in order to achieve a noble gas configuration and become stable.

Well, the "happy" number in chemistry is eight. And alkali metals have one valence electron while halogens have seven so when they combine, the combination has eight valence electrons. This means it is full.

ions are formed based upon the valence electrons of the element and if the element is a metal or a nonmetal. S has 6 valence electrons and needs 2 more to be stable. it is a nonmetal. therefore, taking on 2 electrons gives S a -2 charge
According to my chem book, a transfer of one or more electrons from the metal to the nonmetal often occurs
