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

i don t now

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
