Definition: the possible state for an electron of an atom that is proportional to its distance to the nucleus.

the ratio of the conjugate base to the acid required to attain the desired ph.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

i wish i could but this one is weird give me abc and i can solve it.

idk what is it? is this a question that you know the answer or u dont
