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

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
