2. what happens during ionic bonding?

Explanation:

Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

Not my answer, if you go to the internet and search it up, that's the answer. https://chem.libretexts.org/Bookshelves/Organic_Chemistry/Supplemental_Modules_(Organic_Chemistry)/Fundamentals/Ionic_and_Covalent_Bonds#:~:targetText=Ionic%20bonding%20is%20the%20complete,become%20a%20negatively%20charged%20anion.

The valence electrons are transferred

Explanation:

Let's take NaCl ( sodium chloride) for example. Sodium has 1 valence electron while chlorine has 7 valence electrons. You can find this information on the periodic table. Now the sodium atom loses that electron and becomes a sodium ion while chlorine gains that electron and becomes a chlorine ion. Since sodium loses that one valence electron, it has more protons than electrons, meaning it has a 1+ charge, since there's one more protons than electrons. Similarly, the chloride ion has a 1- charge since the chlorine gains an electron. Notice that if we combine the chloride ion and the sodium ion, the total charge becomes one because -1+1=0. Therefore, NaCl becomes sodium chloride and ionic bonds are the transfer of valence electrons
